Oh, I luurrrve the 'If I had my gun, I'd'a done summat' types. They're soooo...squishy when it comes to what they'd actually do if they had to 'man up' and deal with a real-world live-fire situation..
Listen numbnuts, did I say "everybody"? No, I said "responsible citizens". Most of the massacres in the USA have taken places where firerms are expressly prohibited.
Okay, Saddle bum, let's play Virginia Shooting:
You're a
responsible citizen student on a college campus where it's legal to carry a concealed firearm. You're sitting comfortably in class one day when you hear gunfire, screaming and running feet outside the lecture theatre. You reach into your backpack, produce your sidearm of choice and approach the shut doors of the lecture theatre.
Everything seems to have gone quiet. You open the door a crack and don't see anything, so you open the door wider and step partially out into the hall.
You see two people. A body, apparently a
responsible citizen student, is lying on the floor, shot in the centre of mass, bleeding profusely. Near the body's right hand is a handgun. Standing near, but not over, the body is another apparent
responsible citizen student holding a handgun. The standing
responsible citizen student turns towards you and starts to raise their handgun. Your own weapon is not trained directly on the standing
responsible citizen student. You have 0.5 seconds to decide what to do. What do you do?
