Why are lie detectors still used or pushed to use when its not admissible in a court of law?

Question

Admissible Evidence



Admissible Evidence is 'evidence' that is accepted as legitimate in a court of law. From an Information Security perspective, the types of 'evidence' will often involve the production of a system's log files. The log file will usually identify the fact that a login took place; and certain functions were performed. The issue as to whether or not such a log file is legally admissible, is not clear cut. However, opinion appears to be that as long as a computer record is generated as a normal part of business processing, and the computer and software were working as designed and expected, then it may be admissible. Advice from a lawyer is always recommended.

Answer 2

I have a very good friend who is a polygraph operator. People use them for lots of reasons, but the first that popped into my mind, and made me laugh when he told me, is for testing the veracity of people OUTSIDE of a courtroom, in a non-legal situation (he told me they are used extensively in fishing derbies. Go figure) and for people applying for employment.

The reason, though, the log files admissible, and I think this is really what you are asking, is that (at least in my state) business records kept in the ordinary course of business are admissible.
They are admissible unto themselves, but because they are a form of hearsay, they can't be used to prove what they say is true. Its a weird distinction that took me a long time to get my head around. So if you have a log file admitted, you can use that evidence to prove that testing was done on such a day, in such a way, and that Joe blow passed or failed, but you cannot use the evidence to say that Joe Blow was telling the truth or not.

Answer 3

Exactly because it is not 100% accurate. It is pseudo-science and no better than a 50-50 guess. It may make good entertainment on the Jeremy Kyle show, but any court determining peoples liberty based on hocus pocus risks becoming a laughing stock.

Answer 4

It is an intimidation tool. People sometimes are stupid and actually fall for using on then get pressured by lawenforcement officials to spill their guts .. It is a pyscological tool..
IE----- (If I dont theyll think I'm guilty!! If I do theyll find out I did it !!! AGGHH !! What do I do?)--- Thus Equals psycological pressure.
The average person doesnt know they have the right to refuse one also.. Some people think they can beat them from stuff they saw on TV.
Its just a way to screw with suspects.

Answer 5

Actually, they are admissible in some courts. I practice in Michigan, and their results are used frequently in court when a person fails, and if they pass, more often then not their case is dismissed. (the prosecutor's office is more willing to dismiss a case when it is the state police examiner that administers the poly, and the defendant passes- they can't argue with their own expert).

Answer 6

I've taken several psychology classes, and even though they are not admissible in court, most law enforcement agencies still use them because they can measure the responses that people have when they are lying.

Answer 7

A most useful tool when applied for the true purpose of pursuing direction.

otherwise;

abused by non-paying legal council(s), in that one can find direction without missing tee off time.

Answer 8

I don't see them used often at all outsde the military and intelligence agencies. I can't imagine why anyone else would want to use them; they're pretty unreliable.
