Here's the video of the 75 yo pushed by Buffalo Policeman:
Was he pushed to the ground? I think he flopped. I've seen John Stockton enough to know a flop when I see one.
The guy is in decent shape and tall for a 75 yo. And yes, he admits to protesting for various causes.
He approaches the cops that are clearing out an area. It's obvious "they are on the march." Supposedly curfew started minutes ago. The man has a helmet in one hand and a phone in the other. He stops the cops and touches two with the phone while talking to them.
He may have been pushed by up to three cops. The biggest push is by an officer with a baton. He's pushing the elderly man just like he's be trained - baton across chest.
The man falls backwards but doesn't loose his phone or his helmet. Right before he drops out of frame, it appears that he's going to land on his butt.
Next thing you know he's laying on his back and bleeding out the ear. Strange. From contact to bleeding took about 6 seconds.
