Its a strange world, when you can follow somebody in a car, pick up a gun and get out the car, chase them down, then shoot the person you was following, and then call it self defense.
Not only did he have a history of violence, he even had a restraining order placed against him. This 'tough guy' seems he had something to prove and should never have been allowed to have a gun in the first place.
Zimmerman is not a 'good guy' far from it, he chased down a person and murdered them simply on the assumption that they was 'up to something'. No way in hell was this self defence, if anything it seems Martin (a kid) would have been defending himself against an angry, heavy, guy with a gun. WHO WAS FOLLOWING HIM And they call this self defence?
As for talking about it 'being dark' and all the crap. If the person he shot was a police officer and he made the defence 'It was dark, its not my fault', Zimmerman would be facing life in prison or the death penalty.
