1) Ann Coulter is the only person I've seen say 34. She is hardly reliable. Also, I think she "misreads" the fact that there were 34 witnesses for the prosecution. "Witness" does not mean "eyewitness". I'm sure plenty of people testified about things other than the events of that day.

2) As far as I know it's 7 of 9. Of the two who didn't recant, based on what I heard, one was fingered as the actual culprit (and supposedly bragged about it to others).
