A couple of questions:
Why do your shows have varying camera policies?
And, if you're going to have camera policies, why, for the love of all that's good and holy, can't you post it on the webpage along with other info about the show? So people can make a choice as to whether they want to bring a camera or not? It would save a lot of aggro if we could know ahead of time whether to expect we can take pictures, and whether bringing our camera is going to result in it being locked up in a room somewhere. It's annoying as hell to find out AT the show that cameras aren't allowed.
