I also blame the school, for looking the other way during his serious drug/stolen property/burglary tool issues. They didn't want to skew their statistics of burnt umber kids getting in trouble so they ignored his serious thug problems.
But most of all I blame trayvon's parents. The way they acted like he was a saint was absolutely revolting. The mother in particular, did numerous interviews claiming trayvon had never been in trouble, was an all A student about to enter the air force.
Meanwhile she had kicked trayvon out of her home. Told him find somewhere else to live. Then all the sudden she's mourning the unexpected death of her hoodlum son? Disgusting.
