So now, when the SWAT team shows up to take out the shooter, they end up shooting everybody who is armed because they can't sort out the good guys from the bad guys in an instant.
That's after the students have decimated each other, because they can't tell either.
BTW there was a guy with a gun at the San Bernadino shooting, but he was too afraid to use it because he was afraid of getting SWATted. Well, I doubt his sidearm would be all that effective against AR-15's anyway.
Oh and Bart always says the shooters pick gun free zones, but the first thing the Colorado shooter did was take out the armed policeman guarding the place.
