“Following procedure is a very weak defense.”
That’s utter nonsense. Chauvin was following approved procedures of the Minneapolis Police Department, not the Nazi SS. And there is no evidence the approved procedures caused harm. George Floyd died of fentanyl poisoning, not neck compression. It just looked bad on video; that’s the whole case, which ought to be no case at all in a sane world.
What time was the incident?
What was the official time of death?
That Should be enough to raise “Reasonable Doubt” along with the Training Officers, Training records as well as who made the training decision to go with that particular style of training.
