I keep seeing a lot of George Floyd misinformation popping up on this site. I don't have a medical degree so take what you will. I'm sorry I don't have sources.

Facts

1. George Floyed 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. "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, end 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."

4. 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 the situation was in line with MPD guidelines for ExDS.

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 (and coronavirus), 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 a 105lbs.

7. The county medical examiner's report found "no physical findings that support a diagnosis of traumatic asphyxic or strangulation." Pressure applied to the side of the neck, as in this case, and not to the throat, has little or no effect on breathing. One can easily verify this oneself.

8. The toxicology findings from blood samples collected at 9:00 pm on May 25th, before Floyd died, tested positive for the following: Fentanyl 11ng/mL, Norfentanyl 5.6 ng/mL, Methamphetamine 19 ng/mL, Morphine 86 ng/mL, and Delta-9 Carboxy THC 42 ng/mL. (The amount of Fentanyl is considered a 3x lethal dose or enough to perform hearth surgery on an otherwise healthy person without them feeling a thing.)

George Floyd had

1. 90% blocked left coronal artery (50% needs a stent, 70% needs immediate bypass, 90% is imminent death)

2. 540g incredibly enlarged heart (normal is 300g. Max variance for his height/weight is 510g, which would already result in heart issues common to very large people)

3. 1.2mm:0.4mm severe left ventricular hypertrophy (normal is 0.5mm:0.5mm)

4. History of severe hypertension

5. Sickle cell anemia

George Floyd didn't have;

1. No signs of life-threatening trauma of any kind

2. No compression injuries to neck or chest

3. No occult tissue damage, no bruising

4. No petechial hemorrhaging (hallmark of asphyxiation)

Other things to consider

1. He exhibited signs of a heart attack before being restrained

2. He repeatedly said "I can't breathe" while nobody was touching him

3. He was able to turn his head and talk while retrained, clearly not being choked

4. Police called EMTs within 2 minutes of his heart attack, and upgraded it to emergency within 2 more minutes

5. Police put him in a prone position which is recommended for survival in such medical events

6. Police used an approved neck restraint, which is common because its non-harmful

7. Fentanyl is an opioid, which causes respiratory depression. Decreasing oxygenations which exacerbates sickle cell disease, an dsickled cells tend to clot in narrow passages (like 90% occluded LCA's).
