Remember the guy had full body armour on i including legs and throat.
Unless you had a clean shot through the face and eye mask, even hitting him w a 9mm would not have done much and he would have immediately returned fire and you would have wound up dead.
I’d forgotten about his body armor. Yes, that would make it very difficult. I think physically tackling him might have been the only way.
See, IMHO, this is true statements. Now, if 10 people in that place had ARs or similar rifles, loaded and ready to rock, then the guy would have gone down after spraying less than one full mag. Sadly, this is not where we live nowdays. I would rather sit next to a dozen solid citizens with loaded rifles than a thousand sheeples with not even a decent magnum wheelgun, much less a serious rifle, but again that is not where we live. Sadly.
I maintain that if that little fuzzy headed prevert had opened up at my local gun range, he would have spit blood before he had killed 12 and injured another 50. He might have got a dozen of us, but the other dozen would have perforated him and then pissed into his wounds. But again, this is why there are no mass shootings at gun ranges. The preverts know they won't get far, neither will they walk away in chains.
God Bless Texas.
