Adam, Phil, do you know what Home Office study is being referred to? The
article also mentions (Phil's) recent observation that cameras tend to push
crime between jurisdictions.

It'S spring, and a new crop of police surveillance cameras is sprouting in
cities big and small. New York is installing 500 on street corners; Chicago
is upgrading several thousand; and even the city of Dillingham, Alaska, has
80 - one for every 30 residents.

Many of these newer cameras can pan, tilt and zoom, and are networked
through the Internet, so video images can be viewed and stored centrally.
They are often purchased with homeland security funds, meant for use
against terrorism as well as street crime.
...

But some security experts say the cameras are of limited value - largely in
helping investigators after a crime - and are not cost-effective. They
point to a large study by the Home Office in Britain, which has perhaps the
world's most videotaped population, that found cameras to be ineffective in
reducing crime, except in locations like parking garages. And even
scientists involved in the development of visual recognition software
acknowledge that the programs do not work well enough yet.
