Permitted/banned items lists are often a bit of a mess at sporting events. People pay a lot of money for permission to take photographs and videos of the things. There's even technology specifically set up to bypass restrictions on it, cameras with radios attached so that if they get confiscated the images are already safe off-site spring to mind.

Though with smartphones getting better cameras it's at least understandable that people would get their wires crossed.
