 Well, can you imagine in a court of law if someone was lying, a witness was lying, and you couldn't say, tell them that, you know, you're recording something or you're measuring them, but the information could be given, say, with an earpiece to a prosecutor that would tell him on a scale of, say, 1 to 100, this is a liar or completely truth or whatever or something in between. And he could change the way he's questioning somebody to determine what the truth really is.
