BBC News: Could X-ray scanners work on the street?
X-ray cameras that would “undress” passers-by in a bid to thwart terrorists concealing weapons, could be coming to a street near you, according to reports. Aside from the obvious privacy issues, would such a plan work?
Leaked documents said to have been drawn up by the Home Office and seen by the Sun newspaper say cameras which can see through clothes could be built into lamp posts to “trap terror suspects”.
X-ray type cameras have their place in the security framework but in the War on Terror they would be costly and ineffective if implemented widely like surveillance cameras.
They are effective in situations where specific locations need securing such as airports as they can be used to filter out individuals for additional scrutiny by security guards who are hand to do so.
Surveillance cameras are used in an entirely different manner they are predominantly used as a visible deterrent against criminal acts or as evidence gathering devices for prosecution of criminals after the fact. They are very rarely used to apprehend criminals in the act.
Security expert Bob Ayers, of Chatham House, believes putting an X-ray lens on a lamppost poses all sorts of resource questions.
“Some guy walks past and his picture is beamed back to a control room to say that something is under his jacket. What do you do? Despatch a police car to hunt him down and frisk him?
“The real question is not whether the technology can see something under the clothing. It’s how you respond to it when the technology says there’s something unusual.
This may well have been obtained from leak Home Office documents but I doubt even that incompetent government department would pursue this ill-thought out scheme.
