Heavy-handed security searches of hotel rooms at Defcon/Black Hat
Let's remember that is has been < 12 months since the Vegas shooting, and the biggest question people have been asking (aside from motive) is how a man managed to bring that much firepower into his hotel room and keep it there for so long. Now you have a large and diverse group of counter-culture oriented people bringing large padlocked hard cases to their rooms and declining maid service for days at a time. What did they expect? Of course hotel security is going to be all over that. Its a destination resort for gambling and drinking, have some perspective.
