I don't really believe in psychics. I mean, I believe there are people who say they're psychic, and some of them probably believe they are, but I don't think they have any connection to the spirit world. Because - apart from my religion - I don't believe in the spirit world.
Anyway, I would never employ a psychic to help out on a case. I can't see it ever standing up in court, and that's assuming I would survive the hazing long enough to see the court date. (i.e., I don't think using a psychic would go over too well with the work crew.)
