The use of CCTVs continues to be a hot political debate in the U.K.
The city of London has more than 10,000 closed-circuit television (CCTV) cameras deployed around the city, but the use of the controversial technology does not help solve crime, according to several local politicians.
All cameras installed in London cost taxpayers an estimated £200 million -- approximately $400M USD -- with politicians arguing the city has to re-evaluate the way they are used. According to research provided by the British Liberal Democrats political party, the city districts with the most CCTV cameras also have the worst rates of solved crimes.
"Our figures show that there is no
link between a high number of CCTV cameras and a better crime clear-up rate
," said Dee Doocey, Liberal Democrats spokesperson. "Boroughs with thousands of CCTV cameras are no better at doing so than those which have a few dozen."
Numbers provided by Doocey indicate only one in five crimes are solved in all London boroughs.
London's Scotland Yard is implementing several new procedures to try to improve the effectiveness of the 10,000 CCTVs in place in all 32 London boroughs.
"Although CCTV has its place, it is not the only solution in preventing or detecting crime."
The United Kingdom currently leads the rest of Europe in number of CCTVs in use, with more than one million already in use. The technology has drawn a lot of criticism from some politicians and privacy advocates in the U.K.
A quick Google News search for "CCTV" will indicate a number of British news stories that show how CCTV evidence is being used in criminal cases against suspects. For example, CCTV several school children were caught brandishing an AK-47 on a train station platform. The CCTV cameras also helped police identify London tube-train bombing suspects after the July 7, 2005 attack.

A much more accurate study would have been to compare the unsolved crime rate (and the crime rate in general) in before-and-after version of the same area.
You are very right about that. Looking at the article linked from the story here, it looks like they are comparing crime resolution rates across districts, not over time in each district. That indicates a flawed study at best -- not much of a "study" at all.
