My response to this concept remains the same.
A couple of years after I left college, there was a deadly incident in my fraternity house (yes I was in a fraternity, yes it was a mostly good experience for me personally, yes Greek systems are probably generally bad). I didn't really know either of the people involved. Basically drunk guy comes home. Expects to find leftover sandwich in fridge. Sandwich not there. Pissed off, he pulls out a gun (guns and drunk frat boys are an excellent combination) and fires it at a target on the wall. Bullet goes through wall into bathroom, through next wall into next bedroom, into abdomen of guy in next room. Upon realizing he'd hit someone, the shooter promptly aimed gun at himself and committed suicide. Guy he shot ended up being ok (after major medical attention, of course).
Nobody would have been hurt or dead if not for the presence of a gun.
