Well my son is a former policeman and a member of the Army. He has one but I guess I need one too now, after all this. These freaks are just like the butchers in Baghdad. My heart goes out to normal people there.
You can always keep it locked up and put away and just pray that you never, ever have a situation where you feel you may need it. A disaster could affect any one of us. Even if we don't live in a hurricane or earthquake prone area, if we do any travelling at all, we could all potentially be exposed to this scenario.
