TheBeat reminded me of this idea I've been wanting to discuss.
In Texas, if we carry, it has to be concealed. Not concealing it is a pretty easy way to lose your license. However, there are some states (Arizona? I think) where you are not allowed to conceal it. It has to be carried openly.
I personally think that it is a much better deterrent if its highly visible. Here, if I pull a gun on someone, chances are things have escalated enough that I'm going to kill them. But it may not have even gotten that far if they knew I had a gun on me. Thoughts?
