There's a particular rock in the Atlantic off the coast of Europe and East or Ireland that's been carpet bombed with CCTV cameras. Ask anyone who lives there and they'll tell you that they're still waiting for the reduction of petty crime the cameras were supposed to bring. There always seems to be plenty of money to fund more cameras and more surveillance but never any money to fund the Good Old Fashioned Police Work(TM) needed to follow up on all the crime those cameras see.
