Don't agree with the police tactics but at the same time that little girl is annoying. "Put that on my mama" garbage. Just glad he didn't pull the trigger though. We know how that would have ended.
Notice she didn't say "call my daddy"
Outside of that, I don't agree with the cops cursing, but you can't attempt to surround a cop while he's detaining someone....he's not going to go hand to hand with you...he's going to take it a level ABOVE that based on his assessment of the threat.
I've said it countless times, NEVER EVER try to hold court in the street with a cop. Nothing good can come from that. Follow their orders, and let a judge decide.
