The average Londoner is captured some 300 times a day on CCTV cameras.
But the Metropolitan Police have stepped in to clarify who may, and may not, take photographs. Its latest advertising encourages Londoners to look out for suspicious looking photographers, as they might be "making notes about security measures, like the location of CCTV cameras". (Note to Al Qaida: they are located everywhere.)
Other than, say, photographing the MI6 building, it is legal to take pictures in public places. But police recently forced one photographer to delete pictures of the Ipswich Xmas lights, lest he be arrested, while another was challenged for taking "covert" snaps in a Hull shopping centre.
Standards must be slipping - whatever happened to the hidden cameras of the Cold War?
