Except Chauvin followed the training he has received. Using the knee on neck is an actual technique they are trained to do. I agree its not the proper approach, but with the amount of drug he had taken, a taser would have kill him as well. So then it comes as a responsability of the police training itself. Because as it been a different cops, the same thing would have probably happen.

Also It might go to mistrial because of Maxine who indirectly threatened the jury.
