Should I participate in a lie detector test if asked by police?

Subsequently, when individuals are requested to take part in such examinations, they’re nearly all the time suspects or “individuals of curiosity” – even when the police insist they aren’t.  When police say an individual shouldn’t be a “suspect” it could be simply one other approach of claiming there’s not sufficient proof to contemplate them as one. Nonetheless, as soon as an individual full a polygraph check that will all change – certainly, that’s in all probability the purpose.  It is extremely frequent for police to lack the grounds to arrest somebody till after somebody has accomplished a polygraph examination, even in situations the place an individual “passes” the check or vehemently denies their guilt.

Typically occasions, individuals who see themselves as harmless really feel they need to take part to shortly clear their identify.  It’s human nature to want people, and police, to believe they did not do anything wrong.  This human want in the direction of exoneration doesn’t serve the individual/suspect properly below police investigation.

If one is aware of they’re harmless, that must be sufficient for peace of thoughts.  Making an attempt to persuade police to reverse their suspicions exposes oneself to appreciable danger with little, to any profit.  As indicated under, even when an individual “passes” a polygraph examination, that consequence isn’t admissible in court docket to show innocence anyway.   Additional “passing” a lie detector check shouldn’t be conclusive to police and the investigation will proceed as they see match – besides now police have an announcement that will grow to be related to question credibility at a later date.

From a authorized standpoint, notably if an individual is s suspect, there’s merely nothing to be gained by agreeing to a polygraph examination and an individual takes huge dangers in partaking in such a course of, no matter precise guilt or innocence.

As discovered by the court docket in R v Beland, [1987] 2 SCR 398, polygraph outcomes are inadmissible in court docket as a result of such admission would violate many guidelines of proof, particularly, the rule towards oath serving to, the rule prohibiting the admission of prior-consistent statements and the rule towards bolstering character. Moreover, the polygraph shouldn’t be acknowledged as correct professional proof.  The conclusion of the polygraph examiner can also be inadmissible because it goes to the very coronary heart of what the function of the decide or jury is – to find out what the reality is or the place doubt could lie.
