Closed-circuit TV may aid London bombing investigation

July 8, 2005 (IDG News Service) -- London's network of closed-circuit TV (CCTV) cameras may help investigators track down those responsible for yesterday's terrorist bomb attacks, which have left more than 50 people dead and several hundred injured, police said today.
"There are a large number of CCTV tapes we need to seize and to review," said Andy Hayman, assistant commissioner of the Metropolitan Police, at a televised news conference this morning.
Several thousand video cameras monitor London's underground and mainline rail stations, and many more are perched high above streets and shopping centers. They are seen primarily as a way to deter muggings, street brawls and other antisocial behavior and to monitor the growth of crowds on railway platforms.
The cameras were never intended as a deterrent against terrorist attacks, but they may help investigators to figure out where and when explosive devices were planted and to identify suspects, said a representative from a U.K. consulting company that provides security services to London's transport authorities.
"In terms of terrorism, their primary value at the moment is for post-incident analysis," said the representative, who asked that his company not be identified.
The usefulness of CCTV cameras depends on how they are deployed, said Robert Wint, a spokesman for Verint Systems UK Ltd., which provides some of the equipment for the Underground's CCTV system. In most cases, the cameras film continuously, he said, so investigators should be able to review footage for clues.
Police declined to say if the cameras located where the bombs went off were working or exactly how much film footage they have to review.
The network of cameras has earned the U.K. something of a Big Brother reputation, and civil liberties groups have decried their use as an invasion of privacy.
Forensic evidence gathered at the scene will also be key to the investigations, U.K. Home Secretary Charles Clarke said in an interview with the BBC. "We are looking for a small number of evil needles in a very big haystack,'' he said.

British Prime Minister Tony Blair has said the blasts were likely the work of Islamist terrorists. A group purporting to be related to al-Qaeda's terrorist network claimed responsibility, although its involvement hasn't yet been confirmed.
Initial forensic work suggests that devices packed with less than 10 pounds of explosives were left on the floor of each of the three trains, and on the floor or the seat of the bus, police said today. There is still no evidence that the bus attack was a suicide bombing, police said, though they have not ruled out the possibility.
Authorities considered shutting down London's cellular phone networks after the blasts but decided against it,
