Clear case of the prosecution coaching the witness.

I could qualify as an 'expert witness' having been trained in hand to hand combat in the infantry and spending years as a club bouncer and would tell them the actions taken by Chauvin and the other officers could not cause death under normal instances involving a grown male human being. I am sorry but this is a sham thus far and the in depth examination of the post mortem and expert witness testimony there will be all it takes to request dismissal.
