And someone decides to slaughter the sheep...(somewhat graphic, deal with it or don't click the link)
Remember, this is from the "religion of peace".
Not saying that one "good guy with a gun" could have stopped this slaughter....but then again, he (or she) could have possibly cut down on the number of victims...4 men did this atrocity. 1 man with a spare magazine could have suppressed their fire.
Most concert venues here in the US are "Gun free Zones" too.
