In fact he did, right after he was simply pushed away. It was clearly an accident, not intentional (the fall nor the injury), even though he should have had more sense than to confront in any way an anti-riot unit that has orders to clear the place. With a curfew already in effect.
This only serves as a distraction to the clear MURDER of George Floyd.
He was backing away when he was shoved hard in the middle of the chest.
I’ll make you a deal. We will rerun the scene. You back away slowly and I will shove you hard in the middle of the chest. We will do it five times. I will give you a dollar for every time you do not hit your head on the concrete.
We will disregard the fact that you are not 75 years old and that it isn’t a surprise to you.
You are focusing on his age (which might not be obvious in that precise situation, but that's irrelevant) and disregarding the fact that the shouldn't be there in first place much less approaching forward an anti-riot unit that is clearing the place.
You can argue that maybe curfews shouldn't ever be issued or that anti-riot teams should not exist. Ok, but they do, and they were following orders. Or do you really think the fall/injury was intentional?
This is orders of magnitude away from the George Floyd murder circumstances. Yet some people (and politicians) are trying to put both in the same balance.
