In some jurisdictions--don't know about Florida--the results of lie detector tests are not admissible as evidence. Doesn't mean they're not administered, but the results may not be admissible as evidence. ::runs off to check Florida's rules of evidence:: Here's some quick-and-dirty research. They usually don't come in, it appears. http://www.naplesnews.com/news/2009/jan/23/lie-detector-test-ruled-admissible-rarety-collier-/
This has probably already been discussed but lie detectors are not admissable in court. They are, easilyy (at least in terms of a good criminal mind) manipulated. Plus, if you have anxiety disorders such as I have (panic attacks) then you could give a false reading. I would NEVER regardless of the situation agree to a lie detector. They are NOT scientific evidence by any stretch of the imagination.
