Dan is either oblivious to the fact (or ignoring it) that the neighborhood where this transpired has recently been riddled with a rash of crimes commited by young/teen black males, thus the reason for the increased neighborhood watch. This is, of course, according to over a half dozen different reports from various media outlets, I do not know since I do not live there, I defer to their reports.
Did Zimmerman "racially profile" Martin? Sure, he probably did. He saw a person he did not recognize in the neighborhood, felt there was need for further investigation, and followed. Kinda what a "night watchman" does.
He then found himself confronted by, and attacked by, Trayvon.
Just so things are clear, Trayvon was not the victim here, IMHO Zimmerman was. The reality here is Trayvon was the attacker, who apparently was PO'd that some guy was following him, so he decided to teach him a lesson when he tried to go back to his car. What Martin didn't know is the guy whom he was trying to teach a lesson to happened to be armed.
Net result? One thug dead, one guy's life ruined, race pimps get in spotlight again and try to stay relevant.
