Well yesterday, we saw body cam footage of three cops, in a use of force action (because of fear of life), so embattled with an unruly captive, that 1 had a hand in his pocket, one leaning on the tire with one arm, and the other sat on his feet. So one cop says, "HEY, let's turn hom on his side". In which you hear you a stern NO, in response.
Why did the other cop want to turn Mr. Floyd on his side? Because he knew it was against policy, amd best practices to keep am individual in the probe position for any longer than needed to subdue, amd George was subdued.
Something you have to remember, regardless of on drugs or not, all the prosecution has to prove is that Chauvins actions did CONTRIBUTE to his death.
