Just shoot center mass, body armor or not. Think of the bullet impacts as hitting him with a baseball bat - he might survive, but he's definitely going to lose his concentration and probably his balance. So just keep shooting.
And just imagine if only 1% of the people were armed - 400 people, would mean four people shooting at the bastard. He'd have gone down in a bloody heap long before he could shoot 71 people.
And THEN imagine this actually happened - 4 people shooting a bastard in theater, and taking him out. FROM THEN ON, how many people would pack a gun in a theater? The next bastard who tried it would be shot a thousand times before he could get off his second shot.
And after that, there would NEVER be another gun grabber political attack in America again. The next piece of crap liberal to suggest it anywhere in the country would be run out of town on a rail - as they should be.
I used to think that you were correct. Sadly, you are not.
What would happen would be that the MSM would minimize it or downplay it. Remember the mass shooting outside of Denver that was stopped by the lady shooter in the church? It got the most play.
There was the shooter in the California gun store that was stopped by an armed employee. He had plans for mass murder in his car. It was barely mentioned, and spiked by the MSM.
The MSM and their "progressive" agenda is the cause of 90 percent of our problems today.
