==== What part of ‘stand back’ did the guy on the ground misunderstand? ======

Exactly. That was a pretty weak push by the cop toward someone who was disobeying lawful orders and actually reached out to touch the cop.

It's clear the old guy is very unsteady on his feet. That's why a lot of old people take short staccato like steps. He was pushed backward and was unable to stand on his feet.

What on earth was he doing there?
