Based on the widely circulated eye-witness account of the (himself armed) guitarist Caleb Keeter - in which he recanted his life-long opposition to gun control after BEING in that situation and finding his own gun useless. 

This was a country music show in America. Country music - the stuff gun nuts all listen to, the stuff they blare when they walk into family restaurants with an AR-15 slung to their backs and say they are excercising their "rights"*. There were probably more guns in the crowd than in Paddock's hotel room.

*I put rights in quotes because even in America you don't have a right to carry a gun onto somebody else's private property without their permission. Open-Carry laws don't actually mean the owner of the local McDonalds has to allow you to scare kids with your massive penis-extension hanging out. Indeed, any SANE restaurant owner would call the cops thinking he is about to be the victim of an armed robbery - and if a black man does it, you KNOW he will.
