Not really, Bud. Many venues here in the US stupidly restrict ALL cameras. Even point-and-shoots. Camerasphones? No problem. Makes no sense but it is true. Most cameraphones have lower resolutions than modern point and shoots but it still doesn't explain the idiocy. Especially when you can now get HD video from some devices that won't even set off a metal detector.
I can't speak for the rest of the world but around here they allow cameras because of all the camera phones.
What they don't allow is professional equipment (big lenses).
