Tell you this much Aaron, you go ahead and try to talk the perp to stop, and I will watch from a safe distance. If I have my gun with me, perp will likely be assuming room temperature by the time I am finished.
I immediately moved behind the pillar ~ which suddenly wasn't wide enough.
The deal was a West German undercover cop gave up his cover to seize a gun (very heroically) from a guy who intended to start shooting some of the other people at the table crowded with Turks.
If the guy had gotten off a few rounds he'd hit people BEFORE anyone could do anything. It is still a good idea to be able to shoot back so that further killing does not happen.
I cannot imagine the brain damage that man suffered that makes him think the Texas Tower Killer should have been allowed to continue killing people for the rest of the day. He is sick.
I remember this incident well. Civilians on the ground definately shot back; even before the police responded.
They made the guy keep ducking and diverted his attention. They definately DID help.
