Seems a lot of people think GZ ####ed up that night but the way our system works he goes free
I think so.
You have to know the stakes go up when you enter a situation with a gun. Negligent homicide, I don't know what you'd call it. You just can't shoot someone because you're getting your ### kicked. Where's the line? Someone punches you in the face and you can shoot him?
Sure you can. You can shoot someone anytime you feel you are at risk for grave bodily harm or death, as long as you didn't instigate the conflict. If I'm getting punched in the face and my head is getting beat into the concrete, I'm going to shoot someone. There's too many stories like Bryan Stow's to not think you are at risk of grave bodily harm. Blow's to the head are a very serious issue. It just takes one punch in the wrong spot.
Now, I believe Zimmerman screwed up by getting out of his truck, but that's not enough to call this negligent homicide. There's no evidence proving that he started the fight.
In the TM/GZ incident, do you believe that either TM or GZ would have been killed (or suffered serious bodily harm) had GZ not been armed?
See, that's my issue with what you're describing. I noted above that a confrontation w/ loaded firearm has more potential outcomes that result in death (or serious bodily harm) than a confrontation w/o firearm. I think that this is correct, as all of the potential outcomes w/o firearm remain (e.g. assailant disarms you and neither of you have the gun), and you now have the added number of potential outcomes where one of you has the gun in his/her possession. So, can you convince me that the probability of a catastrophic event (i.e. at least one of you end up dead, or seriously injured) is less in the confrontation w/ firearm than it is in the confrontation w/o firearm? I think that this is true when you're considering confrontations that involve, say, police officers, but I'm not convinced that this is true when we're talking about an ordinary gun owner.
