If guest read the signs outside rides, i will use Demon as an example, you will see that it speciffically states that cameras are not permitted on the ride.
As for it coming back on the operator, there is only so much they can do, while i worked on SP i would have guests on cabin 2 who did not appear to have any loose articles with them when i checked the harnesses, but when i got around to the op panel and looked at the camera that faces C2 i would see that they had pulled a camera out of their pocket. I then had to go and get the guest to leave the camera in the launch area. How are operators supposed to stop that happening?
