I was going to say... staging a jihad attack in TX isn't too bright. Had these guys managed to get into the event, they would have discovered to everyone there was armed.
My older brother and his son both live in Texas. They both have concealed carry permits.
Maybe not everyone there was armed, maybe
Actually the event was held at a school facility. No one but peace officers can carry there. Against the law for ccw holders to have a firearm in a school district facility in Texas.
“they would have discovered to everyone there was armed. “
That’s what the backpack full of TATP was for.
