Function Creep in London Congestion-Charge Cameras
In London (the system was built for road-fare collection, and is now being used for counterterrorism):
Police are to be given live access to London’s congestion charge cameras—allowing them to track all vehicles entering and leaving the zone.
Anti-terror officers will be exempted from parts of the Data Protection Act to allow them to see the date, time and location of vehicles in real time.
They previously had to apply for access on a case-by-case basis.
I’ll bet you anything that, soon after this data is used for antiterrorism purposes, more exceptions will be put in place for more routine police matters.
EDITED TO ADD (8/16): Well, that didn’t take long.
