My experience in having a polygraph test applied to me after the business I worked at was robbed is that the results absolutely have no bearing on how the cops act afterward. They only bring you in for that in order to tell you that you failed, and should confess now in order to secure a lighter sentence. Had I not had a family friend who was an ex-police officer, I would've been absolutely scared shitless during that experience. Even knowing they were going to do it, I was still absolutely terrified. It's a fucking travesty that they are allowed to use pseudo-science mumbo-jumbo to terrify people into confessing. I lost all faith in the US police system in 2001 when I had to go through that. I have zero faith in their ability or even willingness to be 'the good guys.'
