I'm surprised the people blaming Abbott, are not also blaming Trump, or even Bush (might as well).
Anyway, that video is hard to watch, the cops stood out in the hallway and listened to shots being fired and children screaming. Hell, most of them stayed way down the hallway, and many even hid around a corner of the hallway. Just pathetic.
I will say this, you could randomly pick men off the street, arm them, and they likely would have been moved to action once they realized what was going on. These cops were likely NOT cowards, but they were completely bogged down by their own ******* red tape and policies and procedures. In the end, they didn't act like real men.
