Maybe I'm an idiot, but if someone has punched me in the face and is trying to knock me unconscious by slamming my head on the concrete, they're using deadly force on me. My common sense,especially during a beating while calling for help is use anything at my disposal to make the beating end, even if it involves deadly force.
Anyone who would disagree needs to have their nose broken and their head slammed against the concrete repeatedly until common sense allows them to think clearly.
I read a quote from a friend of Zimmerman that Trayvon said to him “Yo gonna die tonight “MF”” as he was beating him.
If that is true, I think Zimmerman was certainly justified in the force he used to stop him.
Maybe Zimmerman can claim he was simply firing a warning shot into the air and could not help it that Trevon was in the line of fire?
