I will not say that I will "never" be in a position that Zimmerman was. I wouldn't have pursued the young man, if that is what happened. I really think there is fault all over the place with this one. The problem is that none of us know exactly what went on that night other than the man Zimmerman killed a young man with a firearm. I really think that a whole lot on the left hung their hats on this case as a stance against the SYG laws, maybe seeing it as an opportunity to lash out against gun owners in general and SYG supporters specifically (look at the initial posts from a year or so ago and note the focus of most of them), though many saw the racism in it from the inception, pointing out Samford's history even then. It was truly an unfortunate situation.
I have been a neighborhood watch person before. I have called the police [sheriff] on strange people (not from here) acting strangely in our town after dark. I have even held a person at gunpoint until the law enforcement official could get here...about 30 minutes to the nearest one at that time. We had caught him in the act of breaking into the one store in our town. The thing is, if that person had tried to leave, I'd have let him. If he had assaulted me and I feared for my life, I would have responded appropriately as well. Fortunately, none of that happened. But I will ever be prepared and fight for the right to be prepared. Unlike some, I think most law enforcement officials are good guys but they simply cannot be everywhere at once. I owe it to myself and my family to be prepared.
