Closed petition Make lie detector tests mandatory when questioning suspects in a serious crime

Closed on

When questioning suspects involved in sex offences, manslaughter, murders, and missing persons, polygraph tests should be a mandatory part of the police interviewing process, even if the crime was overseas. The test should be taken more than once to minimise the chance of false readings.
