I don't know if it was murder. I can even see an argument that, ocne the fighting started, he was losing the battle and felt the need to protect himself.
But to me the issue is, the police told him to back off and he didn't. If he had backed off, this confrontation never would have happened. He bears some responsibility for what ensued due to this fact alone IMO. I am not happy with the idea of neighborhood watch people carrying guns either. And I am not anti-gun.
I don't know, legally, if you can call it manslaughter or murder. No one else will ever know exactly what happened. But SOMETHING is very wrong when one can ignore the police, a person ends up dead, and he doesn't bear any ressponsibility for causing it. Problem is, if it wasn't manslaughter, I don't know what sort of law would apply.
Any of us here with SD training in our MA training knows you avoid confrontation whenever you can. Put yourself in a position where you can avoid fighting whenever possible.
I am not sure how much the media played up the racial issues. Zimmerman isn't white. And one media outlet did cut the police tape to make it sound more racial than it was. I think THEY should face some sort of charges for inciting society by doing this BTW.
But no one won. Not Martin's family, not Zimmerman. He is going to have a miserable life because of this (and he may very well deserve to). Society certainly didn't win.
