I'm sorry folks, but I must agree with Bill Cosby on this. Zimmerman did not need to be carrying a gun.
It was his right, If he felt a need then it was his call. NOT YOURS.
First off, it's his right to carry one, you weren't there so I don't know where you get off saying he did not "need" to be carrying a gun. Secondly, there's a reason why there is a "neighborhood watch" - a lot of apartment complexes, and other residential areas have neighborhood watches and most people who are part of the watch have a license to carry a gun or carry some other kind of weapon. It's stunning to me how ignorant people can be.
So, a person responsible for policing the neighbor hood and with the all to real possibility of running into violent thugs(which Zimmerman did)shouldn't be armed? Since when do you get to tell people whether they can be armed or not? Oh, that's right, you don't get to tell them.
Zimmerman would most likely be dead right now or a brain dead vegetable if he had not been armed, or are you forgetting the part about Zimmerman being the one who was attacked by TM, not the other way around?
