For the keen photographers out there, this article from the BBC has some useful information on when it is legal / not legal to take a picture in a public place (it would appear to be always legal) and when a member of the police can confiscate or ask you to delete an image (when they have a court order).

I can’t help but think back to the concert in St. Helen’s last year where the band’s manager told the security staff “No more pictures” about 5 minutes into Echo and the Bunnymen’s set in the middle of St. Helen’s, leaving them the task of pointing at people with cameras and mouthing “No photos”. It worked fine for the front three rows.

Its one thing to know your rights – its another thing to be able to enforce them in the face of an angry bouncer or policeman.
