I don't see where it would be their business to state what business it is of someone else to be suspicious of someone else or follow them, regardless of whether it was their son or not. "Stalking" is unfounded based on the lack of a charge for it. "Killing for no reason," surely having your nose broken, head beaten into the cement and someone going for your gun is reason enough - remember, it's not your opinion, it's the judge and jury's opinion of the law and all that law states is that Mr. Zimmerman had to have feared for his life when he pulled the trigger. Regardless of whether or not you beat my head into the ground or break my nose, you go for my gun you're dead and I won't think twice of your race, who your parents are, who your brother is, etc.
