Lie detector [sic] tests set to be introduced to monitor sex offenders
"Politicians expected to approve law allowing compulsory polygraph tests of sex offenders released into community [well, of course they are].
MPs are expected to clear the way for the introduction of compulsory lie detector tests to monitor convicted sex offenders across England and Wales from next January.
The national rollout of US-style mandatory polygraph tests for serious sex offenders who have been released into the community after serving their prison sentence follows a successful pilot scheme. The trial was carried out from 2009-11 in two Midlands probation areas and found that offenders taking such tests were twice as likely to tell probation staff they had contacted a victim, entered an exclusion zone or otherwise breached terms of their release licence.
Continuing concerns about the reliability of the tests and misinterpretation of the results mean they still cannot be used in any court in England and Wales.
But it is expected that the compulsory polygraph tests will be used to monitor the behaviour of 750 of the most serious sex offenders, all of whom have been released into the community after serving a sentence of at least 12 months in jail ..."

Sense About Lie Detectors
"Lie detectors have been around for nearly 100 years. Despite debates over their accuracy and the ethics and legality of their use, the public and professionals remain intrigued by them.
Lie detectors mainly consist of polygraphs, voice analysis or brain imaging. These technologies are different but three points are relevant to all:
>They are not accurate.
>They do not measure lies but rather something that could be a proxy for lies.
>They all rely on the deterrent effect (that is, fear of being caught lying)."
