The drugs in Floyd’s system, and his coronary condition are largely irrelevant in this case. Derek Chauvin didn’t know anything about Floyd’s physical health.
Chauvin’s case will be decided on whether his breaking police policy by continuing to apply his knee to Floyd’s neck after Floyd stopped actively resisting (stopped moving and breathing, also) contributed to his death.
Chauvin’s depraved indifference to Floyd’s situation, leaving his knee on his neck for 2:45 after they checked for his pulse is what I cannot see him being able to explain away nor justify.
