Oh Jesus, really? I like you nightmare but this is your logic?
Unless you have a crystal ball and can know with 100% certainty when you would actually need to have a gun with you for protection, how do you know you won't get attacked at the grocery store, or school, or anywhere else you go? I'm not saying it's wise to take a gun everywhere you go, but I don't have a problem with people exercising their right to do so.
