Its a good post but I have one issue!.. You do not need a "conceiled weapon" to tacke or provent someone with the intent to do harm to others. I worked in a major hospital in the US and one evening we had a high crackhead enter with a gun and knife. I watched and tried my best to help as a young intern talked him down from shooting up the ER. When your faced with a situation you just react, and you do what comes by instinct. I give the intern all the credit for he did most of the talking and neither of us wanted any spotlight or to be seen as a hero. Hell, that was my one and only experience, I cant imagine what Police and first responders have to do.
My point is, u dont need a gun to be a hero. United flight 93 is all the reason that is needed...
