They pushed him and caused him to fall over backwards.

He's got stuff in both his hands and he's very clearly not trying to take their weapons away. His hands are roughly at the same height as their "weapons," yes.
Yours is a rhetorically sneaky way of suggesting it was reasonable for them to believe he was reaching for their batons. It's similar to the way LA cops used to murder unarmed people and suggest that they were "reaching for their waistband." Literally anyone whose arms are of normal length is at any given time "reaching for their waistband" if their hands aren't on their heads. Don't be this dishonest, it's pathetic.
