cw, you brought up a great point and I did a little research looking for such case law to support the relevance of a witnesses "stability" in a matter such as this. I was unable to find any ruling in any of the 50 states, as well as federal court (supreme court appeals - 21 rape cases since 1998) where the "mental stability" of the witness was called into question and used as the primary defense. Several attempts, but not 1 was allowed. I'm sure there are a few cases out there (with 1365 rape cases being filed since 1998) that have been able to enter some "stability & credibility" evidence.. but not one where the case was based solely on that. If he doesn't get a change of venue, he's screwed. This is the girls only strike.. and to be honest.. after just loosing her best friend I wouldn't be surprised if a jury has sympathy for her.
BTW, sources are FindLaw.com and CourtTV.com
Good info there Steff, but despite everything we know so far, I don't see him getting convicted, but hopefully I'm wrong if he is indeed guilty.
