Not having armed guards on site, armed with scoped sniper rifles and AR-15's is to blame for this, not the guns. When you gather 30,000 people into a tightly packed area, you have to defend them with armed guards.
One guy with a well placed sniper shot could have taken this guy out within seconds.
And they would find him in the dark how?
Videos showed muzzle flashes. If you have to, shoot at the muzzle flashes. The side of the Mandalay bay resort is lit anyway, a good sniper could have taken him out. You don't think cops are trained in sniping at night?
You only fire at the window thats broken that has muzzle flashes coming out of it. I could see which windows were broken with the naked eye, much less with a high power scope.
Some stupid liberals were asking "what happened to the CC holders, why didn't they shoot back? They are supposed to be heros but were running like pussies".
1. Guns were not allowed at this concert. So CC holders who were actually following the law (yes there are a few of them left) wouldn't have had a gun to shoot back.
2. The shooter was over 400 yards away, CC means a handgun, they are useless at 400 yards.
