You must not go to Vegas much. Vegas is convention central. People who are displaying their wears at industry meetings often bring lots of large creates into their hotel rooms. I have seen creates for large panel TVs and satellite equipment.
I bet there is even a sportsman show where half the ballroom is filled with Hunting equipment including everything for guns.
The reality is that Vegas has a huge amount of security. But nobody thought about this. You would think that mass murder is unlikely when someone is up in their 32nd floor room. Who would think they would hit a concert a block away. And the reality is that the guy only needed one gun and several rounds of ammo.
While all the stupid security people on the news channels are proposing dumb things. The reality is that a guy could do this in New York City any day. Virtually anywhere there is a crowd and a hotel window looking down on it. Just think about Bourbon Street. There is no stopping this with security checks.
Isn’t this pretty much the same way the guy was able to take down 5 cops in Dallas? Or Whitman on the UT tower for that matter.
