There is a video of Floyd acting like something was wrong with him when the cops first got him to the side walk. He seemed to collapse against the wall. Then when they pick him up and start to the police he has a grimace on his face. There is another video shot from a distance where they are walking him to the cop car and his legs buckle under him and the cops end up carrying him over to the cop car. I’m not putting blame on anyone yet because I don’t have all the info, just pointing out it looks like something was wrong with before the cop knee.
Ever had your arms yanked, twisted and ziptied behind your back? It hurts your shoulders & makes you walk funny.
