Oh where to start. Zimmerman was not a security guard. He was a self appointed NW Captain. He did not identify himself to the unarmed boy he shot and killed.
Unless you have a prior dislike or hatred for Obama, him saying if he had a son he would look like Trayvon wouldn't mean anything to you except a father sympathizing with parents of a dead child.
Most of us with children felt broken hearted that a child was dead. Needlessly dead. Color didn't matter, he was a child shot to death before he had a chance to live his life.
The "black kid" was only defending himself from a strange man he did not know, who didn't identify himself and from whom he had already ran away.
How would you feel if it were your unarmed child who was walking where he had every right to walk, not breaking any laws, minding his own business and and was shot dead?
Too bad he wasn't minding his own business. Martin had ample time to go home but chose not to. Apparently he doubled back to confront Zimmerman and physically attack him. That decision cost him his life.
