You can also get negative pressure pulmonary edema working hard to inhale against a restricted airway. I think his death was ago binational of his physical issues and drug abuse not helped by the cops sitting on him. The thing i find inexcusable was the length of time they went without checking on him after he went limp and the lack of trying to render aid once they realized his condition. Murder? i don’t think so. but negligent homicide? I think you could make a good case for it
One of the Police officers stated that he heard Floyd snoring, which is why he was not concerned.
Also, Floyd's neck was turned 90 degrees to the right.
No soft neck tissue was exposed, only taut neck muscles.
Also, the knee restraint hold was described and approved by the Minneapolis Police Manual on the day it was used.
Also, several photographs dispute the claim that a knee was directly on Floyd's neck.
