He could of killed her straight up. In no way am I condoning her wild behavior but that was more than excessive.

A video of a Phoenix police officer slamming a 15-year-old girl to a wall surfaced on the web. The incident happened on January 2011, when the teenager was caught drinking at school. Police were called when the teenager got into a physical fight with her mom. The officer is now being investigated for alleged excessive use of force.

I dont agree with smacking around a young girl… But when are you people going to realize that until we go back to the ways of NOT babying kids…this is what we are going to get. 15 year old girls, drunk in school and drunk enough to hit there own family. Go back to punishing kids and get rid of this false self entitlement, then we can work on cops being physical with them. These days that kid could of had a knife/gun etc and would not of thought twice about killing that copper.
Cops are all assholes! There are the punks like this asshole who sucker punches a drunk teen with her back turned. What a real brave man he is! What strikes me is the other cowardly assholes cops that stood around said or did nothing to stop this punk! Then they wounder why people hate them so!
