I think that's reasonable. Learned from my own experiences I know not to do things to cause trouble with people on the street. I certainly wouldn't be following someone around, or if I were to do that for some reason that I would do it in a more discreet manner than Zimmerman seemed to have.
Honestly some of the things that I've read about this case, not only here although we do have some crazy fuckers on these forums, make me want to get my concealed carry permit as soon as possible. Just the thought that I could be followed around and harassed for no good reason and then be responsible for an ensuing altercation boggles my mind. I would rather be the guy with the gun. In fact I'm going to be the guy with the gun. I've already made the decision because that shit is ridiculous.
