XO's quite right, three is more than enough to hang the guy. It's hard enough to get one woman to come forward (witness the hatchet job on Sharon Bialek) two would seal the deal and three is icing on the cake.
We know there were four because Bialek said she was coming forth for the first time, whereas the third accuser came forward at the same time as the two who settled but decided not to make any claim, undoubtedly out of fear of being treated by the press the same way as Bialek. It's very daunting to be subjected to shit-smearing attacks featuring anonymous "friends" and their quotes plus your whole personal financial history laid out for inspection. Disgusting is the word for it, but not surprising coming from that sleazeball perv.
Four witnesses or three, a pack of lies coming out of the Hermster and an 80K settlement, plus Cain's ass out the door in under three months.
Common sense alone tells you his chances of being innocent are down under one per cent, which is where the "Hail Mary" quackery of a gratuitous VSA comes in. At this point, what's the dumb schmuck got to lose?
