Deep thoughts about Treyvon Martin

Trayvon Martin lost his life in an unfortunate incident. Is it because he was black?
The answer is obvious. Would he have lost his life if he was chinese or Indian origin? I’m not sure. Maybe not. The big question is to ask if USA is really over the racial profiling? Is it acceptable to shoot somebody and say its ok cuz I’ll get away with it.
How the hell can a guy that big feel Threatened by a teenager who doesn’t look physically capable of hitting a grown security man? gosh where is common sense.

Is it believable when some guy who looks like Zimmerman says he acted in self defense against an unarmed teenager? Please share your views.
