Exactly my point. He has a history of violence. Not hearsay, it's in the police records. DWI arrests, DWI class, Assault arrests, Anger management class, Restraining orders for physically assaulting a girlfriend, blaming the girlfriend for the assault. This guy is a real winner. His background alone (which they didn't check but they damn sure checked the black kid's background) should have let not only to an investigation and arrest but for drug testing (which was done on Trayvon). He has a history of substance abuse. Yet he left the police station with his gun that same night.
