Can you take cameras to Qualcomm stadium?

The Wembley website states that you cannot take any "professional cameras or recording devices" into the stadium. I have been to plenty of games and concerts there and seen many compact cameras and camera phones being used. So any standard camera below an SLR seems to be fine. Before I knew this I once made the mistake of taking an 'Bridge' SLR (so not even a full SLR) and I was treated like a terrorist, being pushed into a side room, interrogated for 10 mins, had my camera confiscated and was almost refused entry to the gig even without my camera. They completely refused to accept that Photography can be a hobby as well as a profession. You have been warned!
