When a firearm is pointed at someone and both parties walk away then I can deduce exactly who the rager was.
It goes like this..
Responding Officer: sir, you know this guy is a police officer right??
Assaulted Guy: I don't care who the hell he is.. he pointed a GUN at me!
RO: well, you know that we can charge you with X,X,X, and more X.
AG: I'm not the one who was the xxshole.
RO: look, we can all go home now or we will take you in, your choice. we might even find other things to charge you with. think about it.
AG: that guy assaulted me with a deadly weapon, if yo.....(interrupted)
RO: OK, turn around, hands behind your back.
AG: wait, wait.... ok ok. we can just forget this, right??
RO: yep, be a good boy and don't make a big fuss out of this or we will be looking for you. got it ?
tongue in cheek here, but we all know its really like that.
