A lot of people are uncomfortable taking a polygraph even if they ARE innocent. I think that I'd be nervous about it myself. Is there a way that Raven could arrange to take one on his own at his lawyer's office or something? I remember that John Mason in the ridiculous run-away bride case, (ironically on the same night that Janet was murdered I think), was willing to do something like that - arrange for his own polygraph to include videotaping in his lawyer's office. LE wouldn't accept it but it seems that it would be better than nothing anyway - if for nothing else, to at least prove to his family and friends that he's not afraid to take it. Because it seems to me that no matter his family and friends say, they cannot possibly be 100% convinced of his innocence. The lie detector could change that for him. All things considered, I think that Raven should take a polygraph test.
