Put yourself in the place of one of these women.
Yes, to others there may seem no reason to be scared anymore because he is behind bars for a very long time. However, they will probably have their past lives picked through with a fine tooth-comb by Philpotts lawyers looking for the slightest indiscretion. He has nothing to lose by denying the allegation which means they will be forced to PUBLICLY relive every minute detail about the allegation. And when I say 'minute detail' I mean 'minute detail'!
The defendants lawyer will be out to trip them up in any way they can, no matter how small the detail, and will constantly refer back to this in order to sow seeds of doubt in a jury's mind. Its why a lot of assaults either do not get reported or are retracted before they reach court.
Now considering those points, and bear in mind these women will have already been questioned thoroughly by the police, do you think you would be able to go through that ordeal again in public?
