“Again, control the head, you control the body. We know more now than we did, it appears that the officers responded as trained.”
LOL! No officer is taught to keep a deadly old on after a person goes unconscious.
Procedures mandate immediate release of such holds.
There were 4 officers holding him down, he was facing away from the other officers, per the video I have seen, it was very shortly after the other officer told him of not palpating a heart rhythm, that he released his neck hold. I posted evidence from a training officer. He did as he was trained to do IMO.
