According to the store clerks, George attempted to make a purchase with a fake $20 bill. The clerk refused the money.

George left without incident but decided to hang out in front of the store, just standing around.

In the meantime, just for practice, the clerk notified the police of the incident. The police then rushed right over because, you know, police in big cities are usually free to rush over to check fake $20s from people who have already left the scene. Happens all the time.

Imagine their good fortune to find George still standing there. That’s what most people do after being caught with a counterfeit bill, right? Just walk outside and stand there.

I find it odd that these two men, Derek (the officer) and George, may have known each other well. They used to work together for 17 years, apparently.

I find it odd that the cop had his hands in his pockets while he put his knee on his friend’s throat. Very odd.

I find it odd that they did not just put him in the back seat of the cop car. They were literally standing right next to the door.

I find it odd that a man who couldn’t get air was able to yell out repeatedly for a very long period of time, and did not struggle to live. Why didn’t he call for help with all those people standing around filming him? He just laid there and passively “died.”

I find it odd that they just stood there and let people film this.

I find it odd that most of Derek’s weight is on his right knee, the one on the ground, not the left knee on his friend, George.

I find it odd the paramedics arrived on scene, approached so nonchalantly, then placed Derek’s very much alive (?) friend, George, into the ambulance without any sign of urgency.

I find it odd that Derek’s neighbors never knew he was an officer. They stated they never saw him wearing a uniform coming and going.

I find it VERY odd that a cop started the riots. Thank goodness for an ex who outed him.

I find it odd that nearly everyone who was arrested for rioting and looting were from out of state.

I find it odd that the National Guard was not brought in earlier, and that they were unable to get these riots under control immediately.

I find it odd that these staged events only happen in Democrat run cities.

I find it odd that this “racist” narrative happened shortly after Biden’s racist comment last week. I knew they were trying to distract us from something.

I find it odd that this happened just as COVID loses traction. Social distancing SUDDENLY flew out the window. Let’s hope the masks and fear soon follow.

I find it odd that COVID happened the moment the impeachment failed.

I find it odd the impeachment happened the moment that Russian hoax failed.

Can you see the pattern? Will you continue to chase the well orchestrated carrots? Or is there something in you that will stop for a minute and look for the truth?

Why Derek Chauvin May Get Off His Murder Charge

A deeper look at the policies behind the death of George Floyd

Pictured: Derek Chauvin (left) and George Floyd

The world has united in protest after a graphic video emerged showing a Black man dying under the restraint of a White police officer. The victim, George Floyd, was in clear distress. He was pinned to the ground by three officers, with one officer — Derek Chauvin — placing a knee on his neck. For over five minutes, he tells the officers that he is unable to breathe. George Floyd died as horrified bystanders told the officers they were killing him.

The video is unquestionably horrific.

But in our rush to condemn an aggressive use of force and pursue justice for George Floyd, we have ignored crucial information which is necessary in judging the conduct of the officers. While nothing can absolve George Floyd’s death, these facts do cast doubt on the appropriateness of a murder charge for Chauvin, and paint a more nuanced picture of the events leading up to the tragic encounter.

There are six crucial pieces of information — six facts — that have been largely omitted from discussion on the Chauvin’s conduct. Taken together, they likely exonerate the officer of a murder charge. Rather than indicating illegal and excessive force, they instead show an officer who rigidly followed the procedures deemed appropriate by the Minneapolis Police Department (MPD). The evidence points to the MPD and the local political establishment, rather than the individual officer, as ultimately responsible for George Floyd’s death.

These six facts are as follows:

  1. George Floyd was experiencing cardiopulmonary and psychological distress minutes before he was placed on the ground, let alone had a knee to his neck.
  2. The Minneapolis Police Department (MPD) allows the use of neck restraint on suspects who actively resist arrest, and George Floyd actively resisted arrest on two occasions, including immediately prior to neck restraint being used.
  3. The officers were recorded on their body cams assessing George Floyd as suffering from “excited delirium syndrome” (ExDS), a condition which the MPD considers an extreme threat to both the officers and the suspect. A white paper used by the MPD acknowledges that ExDS suspects may die irrespective of force involved. The officers’ response to this situation was in line with MPD guidelines for ExDS.
  4. Restraining the suspect on his or her abdomen (prone restraint) is a common tactic in ExDS situations, and the white paper used by the MPD instructs the officers to control the suspect until paramedics arrive.
  5. Floyd’s autopsy revealed a potentially lethal concoction of drugs — not just a potentially lethal dose of fentanyl, but also methamphetamine. Together with his history of drug abuse and two serious heart conditions, Floyd’s condition was exceptionally and unusually fragile.
  6. Chauvin’s neck restraint is unlikely to have exerted a dangerous amount of force to Floyd’s neck. Floyd is shown on video able to lift his head and neck, and a robust study on double-knee restraints showed a median force exertion of approximately approximately 105lbs.

Let’s be clear: the actions of Chauvin and the other officers were absolutely wrong. But they were also in line with MPD rules and procedures for the condition which they determined was George Floyd was suffering from. An act that would normally be considered a clear and heinous abuse of force, such as a knee-to-neck restraint on a suspect suffering from pulmonary distress, can be legitimatized if there are overriding concerns not known to bystanders but known to the officers. In the case of George Floyd, the overriding concern was that he was suffering from ExDS, given a number of relevant facts known to the officers. This was not known to the bystanders, who only saw a man with pulmonary distress pinned down with a knee on his neck. While the officers may still be found guilty of manslaughter, the probability of a guilty verdict for the murder charge is low, and the public should be aware of this well in advance of the verdict.

While we should pursue justice for George Floyd, we should be absolutely sure that we are pursuing justice against his real killers. A careful examination of the evidence points to the procedures and rules of the MPD, rather than the police officers following these procedures and rules, as the real killers of George Floyd. If anyone murdered George Floyd, it was the MPD and the local political establishment. This is why Attorney General Keith Ellison has expressed how difficult a conviction will be.

“Trying this case will not be an easy thing. Winning a conviction will be hard,” Ellison said.

There is still much to the case that remains unknown. As new information emerges, we should adjust our view accordingly. But a close inspection of all current information does not point to a murder charge being appropriate.

1. George Floyd’s symptoms started well before being restrained to the ground

Mr. Floyd stiffened up, fell to the ground, and told the officers he was claustrophobic […] Mr. Floyd did not voluntarily get in the car and struggled with the officers by intentionally falling down, saying he was not going in the car, and refusing to stand still […] While standing outside the car, Mr. Floyd began saying and repeating that he could not breathe.

From the 911 transcript, we know that George Floyd was acting “drunk” and “not in control of himself” before the police were called. The 911 caller is concerned that such an “awfully drunk” man would attempt to operate a vehicle. This is an important departure from the earlier media reports, which indicated the officers were only called over a counterfeit bill.

“Um someone comes our store and give us fake bills and we realize it before he left the store, and we ran back outside, they was sitting on their car […], and he’s sitting on his car cause he is awfully drunk and he’s not in control of himself” […] He is not acting right […] and [he’s] not acting right so and [he] started to go, drive the car.”

This information on its own is of no significance. In fact, aggressively restraining someone who is experiencing distress only makes that restraint all the more heinous. But as will be seen later, when this information is seen in light of George Floyd’s behavior, it led the officers to suspect he was suffering from ExDS — a far more dangerous scenario than simple distress.

2. The Minneapolis Police Department policy authorizes neck restraint for actively resisting suspects

a response to police efforts to bring a person into custody or control for detainment or arrest. A subject engages in active resistance when engaging in physical actions (or verbal behavior reflecting an intention) to make it more difficult for officers to achieve actual physical control.

And passive resistance, defined as follows:

a response to police efforts to bring a person into custody or control for detainment or arrest. This is behavior initiated by a subject, when the subject does not comply with verbal or physical control efforts, yet the subject does not attempt to defeat an officer’s control efforts.

Passive resistance is when a suspect is non-compliant in an arrest, but will not act to stop an officer from enacting an arrest. Imagine a child in a supermarket who has a meltdown and drops to the floor — this is passive resistance, as guardian can easily pick up the child. Now imagine a child who not only drops to the floor but pulls against their guardian. This is active resistance.

The MPD allows the use of force in action resistance. Relevantly, the MPD allows neck restraint. It is defined as:

Non-deadly force option. Defined as compressing one or both sides of a person’s neck with an arm or leg, without applying direct pressure to the trachea or airway (front of the neck). Only sworn employees who have received training from the MPD Training Unit are authorized to use neck restraints.

There are two types of neck restraint. What we are interested is in conscious neck restraint, defined as:

The subject is placed in a neck restraint with intent to control, and not to render the subject unconscious, by only applying light to moderate pressure.

The Conscious Neck Restraint may be used against a subject who is actively resisting.

We know from the original government complaint that Floyd was actively resisting, because they admit as much:

Mr. Floyd actively resisted being handcuffed.

We also know from the original complaint that he resisted again:

The officers made several attempts to get Mr. Floyd in the backseat of squad 320 from the driver’s side. Mr. Floyd did not voluntarily get in the car and struggled with the officers by intentionally falling down, saying he was not going in the car, and refusing to stand still.

While standing outside the car, Mr. Floyd began saying and repeating that he could not breathe. The defendant went to the passenger side and tried to get Mr. Floyd into the car from that side and Lane and Kueng assisted.

The defendant pulled Mr. Floyd out of the passenger side of the squad car at 8:19:38 p.m. and Mr. Floyd went to the ground face down and still handcuffed

The three officers were unable to keep him in the police car. The little video evidence we have indicates that there was a struggle. “The defendant pulled Mr. Floyd out of the passenger side of the squad car” likely because they were unable to close the squad car door due to his resistance. A longer video was posted by the popular activist Shaun King which indicates a struggle. Shaun King believes this video shows the officers beating Floyd, however the government (who has access to the body cams) did not write this in their complaint (which they would, as it would help their case).

There appears to be two cases of active resistance, including immediately prior to prone restraint. As such, neck restraint was permissible in order to control George Floyd. Remember that the MPD guideline is to use light to moderate force. An officer placing a knee on a suspect’s neck does not mean he is exerting full force, and there is evidence that light to moderate pressure was used on Floyd. Given that Floyd was saying he couldn’t breathe while resisting being placed in the police car, the officers could not reasonably believe that light to moderate pressure would cause his proclaimed symptoms.

For reasons not yet known, Minneapolis is refusing to release the officers’ body cams of this moment. This information is important in order to determine how Floyd was acting the exact moment the officers pulled him from the police car. It is unconscionable that this information has not been released to the public. We must assume, given all relevant information already known, that their reason for pulling him out of the car was his continued resistance as noted in the government complaint.

(Note: the original page for the MPD detailing use of force has been wiped. Here is an archive hosted by — for some reason — the San Francisco police department. And here is an archive of the archivejust in case.)

3. The officers reasonably determined that George Floyd was suffering from Excited Delirium

The report specifies the nature of ExDS, the symptoms of ExDS, as well as what police officers should consider when dealing with those they suspect of suffering from ExDS. The report is long. First, let’s backtrack and establish that the officers did in fact suspect excited delirium. WaPo hosts the original government complaint:

Officer Lane said, “I am worried about excited delirium or whatever.” The defendant said, “That’s why we have him on his stomach.”

It must be understood that the public does not yet have enough information to conclude whether the police were accurate in their assessment of ExDS. We have some information indicating that the determination is correct, but absent the full body cam recording, we are unable to make a complete judgment on this point. This is discouraging, because the entire case rests on this point. We know that two officers believed he was experiencing ExDS, and that the other two officers did not comment to the contrary. We also know that George Floyd had some symptoms of ExDS, but we do not know if he had all symptoms of ExDS, or if he had any symptoms indicating the contrary. Below are the symptoms, affixed with whether we know he experienced the symptom or not:

  • Sweating [Y]
  • Police Noncompliance [Y]
  • Lack of Tiring [Y]
  • Unusual Strength [?]
  • Pain Tolerance [?]
  • Tachypnea [?]
  • Tactile Hyperthermia [?]
  • Bizarre behavior generating calls to police [Y]
  • Suspected or known psychostimulant drug or alcohol intoxication [Y]
  • Erratic or violent behavior [?]
  • Ongoing struggle despite futility [Y]
  • Yelling/shouting/guttural sounds [?]
  • Agitation [Y]
  • Inappropriately Clothed [N]
  • Mirror/Glass Attraction [?]
  • Suspected or known psychiatric illness [N]
  • Failure to recognize or respond to police presence at the scene [likely N]

Some of these symptoms can only be determined from body cameras. Unfortunately, other symptoms can only be determined by the officers’ account. It is not possible to know whether he was experiencing tactile hyperthermia except by asking the officers who had touched his skin. We will have to work with these limitations in our analysis of the event. However, that both the brand new officer (Lane) and the veteran officer (Chauvin) suspected ExDS is not poor evidence. And that no officer objected to this determination must also be considered.

There are also symptoms that we know in hindsight, but which the officers did not know. For instance, George Floyd had a history of stimulant abuse, as detailed in his arrest log, with four previous arrests involving drugs.


The White Paper goes on to describe the dangers of excited delirium, both to the officer and the suspect. This information is important, and explains why the officers responded as they did:

Given the irrational and potentially violent, dangerous, and lethal behavior of an ExDS subject, any LEO interaction with a person in this situation risks significant injury or death to either the LEO or the ExDS subject who has a potentially lethal medical syndrome. This already challenging situation has the potential for intense public scrutiny coupled with the expectation of a perfect outcome. Anything less creates a situation of potential public outrage. Unfortunately, this dangerous medical situation makes perfect outcomes difficult in many circumstances.”

  • “LEOs must also be aware that remorse, normal fear and understanding of surroundings, and rational thoughts for safety are absent in such subjects.”
  • “ExDS subjects are known to be irrational, often violent and relatively impervious to pain. Unfortunately, almost everything taught to LEOs about control of subjects relies on a suspect to either be rational, appropriate, or to comply with painful stimuli. Tools and tactics available to LEOs (such as pepper spray, impact batons, joint lock maneuvers, punches and kicks, and ECD’s, especially when used for pain compliance) that are traditionally effective in controlling resisting subjects, are likely to be less effective on ExDS subjects.”
  • “The goals of LEOs in these situations should be to 1) recognize possible ExDS, contain the subject, and call for EMS; 2) take the subject into custody quickly, safely, and efficiently if necessary; and 3) then immediately turn the care of the subject over to EMS personnel when they arrive for treatment and transport to definitive medical care.”
  • “In those cases where a death occurs while in custody, there is the additional difficulty of separating any potential contribution of control measures from the underlying pathology. For example, was death due to the police control tool, or to positional asphyxia, or from ExDS, or from interplay of all these factors? Even in the situation where all caregivers agree that a patient is in an active delirious state, there is no proof of the most safe and effective control measure or therapy for what is most likely an extremely agitated patient.”
  • “There are well-documented cases of ExDS deaths with minimal restraint such as handcuffs without ECD use. This underscores that this is a potentially fatal syndrome in and of itself, sometimes reversible when expert medical treatment is immediately available”.

Each of these bullet points is of the utmost importance in understanding Chauvin’s state of mind. These points must be re-read and thoroughly understood before pronouncing judgment on an officer who was simply following these statements during the arrest. If you are skimming this article I advise you to spend time on these bullet points. Remember: the officer’s job is to follow protocol, not to re-write protocol during an arrest. It is the politician’s job to ensure that the protocols are correct, no the police officer’s.

There has been some controversy in the media regarding the legitimacy of ExDS as a true medical condition. It should be mentioned that ExDS is recognized by the American College of Emergency Physicians as a true medical emergency, and ACEP played a role in drafting the White Paper for ExDS. But regardless of its legitimacy, ExDS is recognized by the Minneapolis Police Department. It bears repeating that Officer Chauvin is not tasked with determining the legitimacy of the syndromes which his department and local government already recognizes. Any question of the legitimacy of ExDS must be lodged against the government of Minneapolis — Mayor Frey — and the MPD, not Officer Chauvin.

4. Neck restraint is common in ExDS, and ExDS suspects have died in all types of restraint

Lane asked, “should we roll him on his side?” and the defendant said, “No, staying put where we got him.” Officer Lane said, “I am worried about excited delirium or whatever.” The defendant said, “That’s why we have him on his stomach.”

This excerpt is of twofold importance. First, it demonstrates that two officers suspected excited delirium. Second, it demonstrates that Chauvin was restraining Floyd in this position because he suspected excited delirium (“that’s why we have him on his stomach”). Restraining an individual on his stomach is common in ExDS encounters. This is called “prone restraint”. In fact, it is often the recommended form of restraint until the officers can safely put the suspect in a different position:

As mentioned before, people experiencing EXD are highly agitated, violent, and show signs of unexpected strength so it is not surprising that most require physical restraint. The prone maximal restraint position (PMRP, also known as “hobble” or “hogtie”), where the person’s ankles and wrists are bound together behind their back, has been used extensively by field personnel. In far fewer cases, persons have been tied to a hospital gurney or manually held prone with knee pressure on the back or neck.

Two years ago, the 8th circuit ruled on a case involving both prone restraint and ExDS, writing that officers are entitled to qualified immunity in cases involving prone restraint, specifically denying 4th amendment privilege against excessive force:

Officers determined that keeping Layton in a prone position was best given his continued resistance, and Baker pressed Layton’s shoulders to the ground while Groby held Layton’s thighs […] this court has not deemed prone restraint unconstitutional in and of itself the few times we have addressed the issue […] Under these cases, there is no clearly established right against the use of prone restraints for a suspect that has been resisting.

Now, qualified immunity is just that: qualified. The court ruled that prone restraint is not necessarily excessive in suspects who have been resisting arrest, even if that suspect is experiencing ExDS. This does not mean prone restraint is always justified, but that it isn’t always unjustified. We still must examine the use of prone restraint on a case-by-case basis.

Informational Asymmetry: what the police and EMTs know, and what the public knows

4.1 ExDS Encounters Explored

Willard Truckenmiller

In the case of Truckenmiller, it is unreasonable to assume the police acted on prejudice — Truckenmiller was a colleague and police officer. It is unreasonable to assume that his cardiac arrest was due to use of force, because he was not held in prone restraint and was quickly given ketamine by the EMS. Despite all of this, Truckenmiller experienced trouble breathing, had a heart attack, and died. This demonstrates that ExDS is “potentially fatal syndrome in and of itself”, as the white paper used by the MPD notes. It is also proof that ExDS deaths are not necessarily caused by excessive force or prejudice.

Roy Scott

The Roy Scott video — linked above — may just be the best case recorded of how police should deal with ExDS. Everything they did was correct. They went above and beyond in deescalating the situation. The officers had compassion for Roy Scott.

But Roy Scott still died. How?

As the Journal of Emergency Medical Services notes,

“The usual response by subjects to restraints is to either accept that fighting is futile or continue to be verbally abusive. The patient with excited delirium, however, continues to fight the restraints until cardiac arrest occurs.”

This is what happened to Roy Scott. It did not matter how the officers restrained him, because he would fight against the restraints past the point of exhaustion and into cardiac arrest.

More Cases of Note

  • In this case from 2011, the officers used a taser and knee-to-back prone-restraint.
  • In this more recent video, it takes six officers, a taser, and multiple batons to restrain the suspect. Even with six officers restraining him, he is still able to get halfway up. At 6:14 in the video, a Black police officer kicks the suspect near the head and then applies force near the suspect’s neck — this is appropriate use of force, even though it appears unnecessary, because the suspect was an extreme threat. This particular ExDS suspect was able to cause facial injuries to the officers despite being overpowered 6-to-1. As the white paper notes, ExDS suspects often “show signs of unexpected strength”.

A Parallel Case: Donald Lewis

Out of all the cases of ExDS and prone restraint available, the Donald Lewis case most clearly mirrors the George Floyd case. Donald Lewis was a white man suffering from excited delirium.

The police first decide to use verbal deescalation. This doesn’t work, as he runs into traffic. He says he is going to die while being restrained by the police. From 1:50 to 2:40, we see an officer use knee-to-neck restraint. Lewis’ condition does not deteriorate from prone restraint, and he continues actively resisting arrest. They then use zip ties and hobble prone restraint. At 3:50 he tries to bite the officers (this is especially dangerous for officers who would prefer not to risk exposure to HIV or hepatitis). At 4:04 he appears to call for his mom. At 5:25 a Black police officer uses knee-to-neck restraint against the white suspect. The Black police officer resumes this position seconds later. The suspect dies in this position.

The parallel to our current case does not end here. An official autopsy declared cause of death “sudden respiratory arrest following physical struggling restraint due to cocaine-induced excited delirium.” The legal team hired Dr. Michael Baden, who testified that Lewis died from “asphyxia caused by neck compression.” Baden is the same medical examiner who was hired by the George Floyd family, and made a similar finding. Baden is also the same medical examiner who was hired for Eric Garner, and declared death by “compression of the neck”. Baden is also the same medical examiner who was hired by the Brown family to examine Michael Brown, and Baden found that Brown died while surrendering, an assertion totally disproven by a DoJ investigation spearheaded by AG Eric Holder under Obama. Suffice it to say, Michael Baden has a very specific interest, and a very tenuous track record. The Court will be aware of this when weighing the autopsies.

After recruiting Baden, a suit against the police was filed. As per CSMonitor,

The 11th Circuit rejected the contention that hogtying was unreasonable once Lewis was already handcuffed and his legs shackled. “Even though most of the officers in this case testified that Lewis was not a danger to them and was merely resisting arrest, he was, as the district court described, ‘an agitated and uncooperative man with only a tenuous grasp on reality,’ ” the appeals-court panel said. […] The panel concluded: “Because of his refusal to sit upright and his inability to remain calm, Lewis remained a safety risk to himself and to others.”

A case of note in a scientific journal

This case study presents a 37-year-old male who was experiencing excited delirium (ExD) and died in a county jail 4 days after being taken into custody. The male died in a jail observation cell without having been restrained and was not under the influence of a drug stimulant. The subject had a documented psychiatric history of bipolar disorder and schizophrenia and was known to consume marijuana, cocaine, and methamphetamines. This case illustrates the pernicious effects of ExD and how its lethality can be delayed when many cases involve drug use and use of force where subjects die shortly thereafter. Implications of ExD for correctional agencies and efforts of responding to it in correctional and law enforcement contexts are discussed.

4.2 What do EMS personnel think about ExDS?

The two top responses to this question are illuminating:

EMS personnel answer, “What is your excited delirium story? What tactics would you recommend for handling such individuals?

5. George Floyd had a potentially lethal amount of fentanyl in his system, a history of drug abuse, and two serious heart conditions — resulting in an unusually fragile condition

  • Fentanyl 11 ng/mL 2.
  • Norfentanyl 5.6 ng/mL 3. 4-ANPP 0.65 ng/mL 4.
  • Methamphetamine 19 ng/mL

This level of fentanyl is dangerous. One review of fentanyl overdoses found a median amount of ng/mL in an overdose to be approximately 10 ng/mL:

Despite the ubiquitous presence of multiple drugs in these decedents, the effects of fentanyl were evidently so strong that there were no statistical differences in the fentanyl level (mean and standard deviation) with or without the presence of these co-intoxicants. The range of fentanyl levels was wide, from 0.75 to 113.00 ng/mL, with an average of 9.96 ng/mL.

Compare this information to an article published in Frontiers of Physiology detailing medical findings in ExDS deaths:

Many patients with excited delirium also have significant cardiovascular and psychiatric diseases. Autopsies often reveal severe atherosclerosis, cardiomyopathy and diabetes. Cardiomyopathy results from chronic cocaine and methamphetamine abuse. Atherosclerosis and diabetes can also be the result of smoking, obesity and a lack of overall health care. The combination of the metabolic arrest with severe cardiovascular disease makes a successful resuscitation highly unlikely.

To be clear: this information cannot be considered relevant in judging the officer’s actions. It is only relevant in determining Floyd’s cause of death, as well as the probability (in hindsight) of George Floyd experiencing ExDS. The actions of the police are never justified in hindsight, but must always be justified given what the officers knew firsthand. With that said, if we are determining the likelihood of Floyd dying from excessive force rather than an especially fragile cardiovascular system, it is minor relevance.

6. There is reason to believe Chauvin’s knee-to-neck restraint did not exert a dangerous amount of force

Remember what we know about ExDS: the suspect struggles with restraint regardless of restraint used. That Chauvin has his knee in a position to exert force if the suspect tries to flee does not mean that he is exerting force the entire time. The knee is there to prevent Floyd from getting up, not from pushing Floyd into the concrete. This is a preventative force position rather than an aggressive force position.

It is, of course, impossible to know just how much pressure Chauvin is exerting in this encounter. He could be exerting only as much force as is required to keep him down. And he could be exerting maximal force. How can we know?

Well, there is one study on the weight of a single-knee and double-knee restraint on the body. On average, single-knee restraint distributes around 70 lbs of force. But Chauvin, for most of the arrest, was engaged in a double-knee restraint position. According to the study, the double-knee position (which Chauvin uses) produces a median force of 48 kg, or 106 lbs. This force would be distributed between the side of his neck and back, unless Chauvin were consciously applying more force in one of these locations. If the force applied were split evenly, that is only 53 lbs of exertion spread across the side of Floyd’s neck. This amount of force, while uncomfortable, is not enough to stop a suspect from breathing and not enough to cut off blood flow to the brain.

But let’s take a look at that study again. The study concludes that the double-knee weight was exactly 23.3 kg plus 24% of a specific LEO’s body weight. Some preliminary information indicates Chauvin is 156 lbs, which is a reasonable estimate, as the footage shows him to be thin and of average height. This means Chauvin was exerting 90 lbs in the double-knee position, for 45 lbs exerted spread across the back and the neck (implying balanced force). 45 lbs is definitively insufficient to restrict breathing or blood-flow in the neck. The other officers are of a similar build.

A Minneapolis-based Study

There are 800 LEOs in Minneapolis. The study has 41 participants, meaning 5% of the officers in Minneapolis participated in the study. If you are an officer in the MPD and you spoke to 9 other officers about the use of prone restraint, the probability is that one of you would have been a participant. It’s probable that Chauvin knew about this study. With four officers involved in Floyd’s arrest, there’s roughly a 21% chance that one of them was a participant in the very study.

The conclusions of the study are enough to exonerate the officers from a murder charge:

  • “Our data do not support the hypothesis of restraint asphyxia.”
  • “When a cause of death cannot otherwise be determined, positional asphyxia is often suggested […] Proponents of this theory often hypothesize that subjects restrained prone, with applied downward weight force, hobbled, or in maximal restraint (restrained on their stomach with hands and wrists secured to the handcuffs) were unable to breathe because the position caused chest wall and abdominal restriction that prevented adequate expansion of the lungs. Subsequent rigorous scientific studies, however, using sophisticated measurements have debunked the positional or restraint asphyxia hypothesis because the prone position does not produce respiratory compromise.”
  • “To date, none of the published human clinical studies, or epidemiological studies, support the hypothesis that the pronerestraint position causes or contributes to ventilatory compromise”
  • “DiMaio and DiMaio observed that acceptance of the concept of positional asphyxia as the cause of death in restraint associated deaths often involves the suspension of common sense and logical thinking. Further, other researchers have commented that positional asphyxia is an interesting theory unsupported by the experimental data. Nor are significant changes in cardiovascular measures found.”

The prosecution is going to have tremendous difficulty proving murder, when Chauvin likely knew of the scientific research indicating that prone restraint is not excessively dangerous to the suspect’s cardiovascular health.


A note on the analysis made by the New York Times

  • The NYT shows Floyd being cuffed behind his back, but then cut the footage so that you do not see the struggle that occurred while he was being cuffed.
  • The NYT mentions complaints made against the officers. However, the NYT does not mention that only one of these complaints was found to have merit against Chauvin, when he asked a woman who was speeding 10 MPH over the limit to step out of her car. The NYT omits the average number of complaints against officers, which is approximately one every 3 years. The NYT also omits that Chauvin obtained two medals of valor, which was ironically reported by the NYT elsewhere.
  • The NYT says “we don’t know why” they pulled Floyd out of the car. This is misleading, as we know they were unable to keep him detained in the squad car.
  • The NYT omitted that Floyd was able to lift up his head and neck.
  • The NYT omitted — completely — that the officers believed he was suffering from ExDS. (This is not a joke. The NYT omitted the linchpin of the case.)
  • The NYT ignores his history of drug use, his two heart conditions, as well as the fentanyl found in his system.

 

 

This is very interesting.
Still a tragedy.
