Self-defense? Self-defense assumes there was an aggressor present. There was and his name is George Zimmermann...NOT Trayvon Martin. O.J. got out of the car and pursued Trayvon. The police told O.J. to stay in the car. He didn't!
"F*cking punks! These assholes, they always get away"! The details of what actually happened after that, no one knows, except Trayvon Martin and he is dead!
