I think this whole event poses a really good question. Where do you draw the line between defending your life with lethal force and just living your life. Like someone posted above, Sure you could never leave your house and never have to worry about getting into a violent situation. But for obvious reasons that won't work. On the flip side if you go pick a fight with someone that you started and then shoot that person in self defense, that isn't right ether.
Unfortunately i believe that this verdict says the second option is ok.
