Police Urged to Try out New Lie Detectors
Byline: Mike Hornby
RESEARCHERS have developed lie detector tests to help police prosecute criminals for the first time in the UK.
Detectives in Merseyside and Cheshire have been asked to test the lie detection equipment to interrogate suspects.
Liverpool University is talking to the forces about real interview tests of a new system that looks for clues from involuntary gestures.
If the tests go ahead,it will be the first time police in the UK have used lie detection technology.
Liverpool psychology professor Ian Donald, one of the researchers involved, said a great deal of interest had been shown in the device called Silent Talker.
The lie detector uses a video camera linked to an artificial intelligence system that spots small tell-tale movements people make unconsciously when they lie. Professor Donald said: ``We are talking to very senior people but it is very informal at this stage.
``Possible police forces are Cheshire, Greater Manchester or Merseyside. ``We are also going to contact the Association of Chief Police Officers and our aim is to trial this in real interviews.''
The system would only be used in interviews with the consent of suspects and their lawyers. A change in the law would be needed for the results to beadmissiblein court. …
