Well..., remember that cheer competitions are private events... even though there are hundreds of people in an arena - they are private events run by a business that can make rules that they see fit to protect their product (the a Cheer competition) Most arena events have a no camera rule, as well as the arena itself. It's not the same as using your camera out in a pubic location.
I completely understand that. BUT, you/EPs are allowing still cameras and nixing video because of the money you/EP are trying to make! How about in your next contract with an EP you allow 2 "Gym" photographers to take pictures and video of their teams only? Charge them for the right to do it and you make money for nothing other than allowing the people who pay for the sport to video their own kid!
