The Guardian in the United Kingdom has an editorial about personal privacy and camera surveillance (a.k.a. CCTV) in the country:
The authors of section 44 of the 2000 Prevention of Terrorism Act did not intend to mandate the systematic harassment of photographers. The law gives police the power to stop and search people, without suspicion of criminal intention, in any area considered a possible target for terrorist attack. […]
The New Review today reports how a rising tide of suspicion is threatening the art of street photography. Anti-terror law is only part of the picture. […]
Meanwhile, CCTV cameras belonging to private and state bodies are constantly capturing images of the public, with no obligation to respect privacy or seek consent.
The ubiquity of the camera, whether mounted on government buildings or in a mobile phone, is a defining feature of our lives, but we have yet to settle the laws and protocols that should govern their use: what is public, what is private, what is fair game for a snapper. It is clear, however, that the balance is currently skewed the wrong way. Moral right gives citizens possession of the streets. Governments and corporations should ask permission to take our pictures if they must, not the other way around.
