I went to the show today. They had an audible recording playing over the loud speakers as you approached the security gates that said specifically that no weapons, fire arms or knifes in any fashion were allowed. Then they had barrels strategically placed near the lines where people could dispose of their weapons (and lighters) before they got to the security check. There was a cadet manning every barrel to make sure no one took the loot. I asked one what they would do with all the weapons and he told me that they take them all and blow them up...
Thought that was interesting.
