I fail to see the gun connection in this thread.
Regardless, some audio would have been nice. The guy was obviously posturing to the officer right before he was pushed. In my department we are required to reach a level of Active Aggression from a subject before we outright strike them. Active Aggression doesn't necessarily require that the subject strike the officer, so much as give an obvious sign that he is about to (ex: blading one's body and balling up a fist towards the officer).
That isn't quite the case here in so far as I can tell, but I'd still like to know more background about:
1) What the guy was saying to officers, if anything
2) What he was wanted for, if anything
3) What the police were telling him, if anything
If I was approaching someone that I was looking for on a felony charge and they disobeyed my orders, then "got in my face", it would almost certainly end up in a hands-on situation.
