This right here. A lie detector test can't be used in court but the police still believe in them. So if he took it and passed it then the police should have been wholeheartedly behind him just as if he had failed it they would have been all over him.Tisdale’s mom said he didn’t have a gun. He passed a lie detector test some say it didn’t matter. But if he failed I would bet some folks would think it mattered.
