I attempted to go last year until printed on the parking tickets it stated that any Professional looking camera equipment is liable to be confiscated and mobile phones only were permitted
I'm guessing this is ridiculous & impossible to enforce
It's is held on PUBLIC land and legally they have no right, under English law, I took this from a statement made by Association of Chief of Police Communication Advisory group for England, Wales and Northern Ireland
" There are no powers prohibiting the taking of photographs, film or digital images in a Public place. Therefore: members of the public and press should not be prevented from doing so"
When I cancelled my tickets ( without a refund) I questioned the legality of their statement, quoting the above Police Communication
I received no explanation, in fact I received no response in any shape or form
I'll not be attending any time soon
