Maybe so, but that's not the issue at stake here.
Would you wager your house that DSK ends up looking at rather more than three years though? Neil and Christine Hamilton may be an extreme example, but the point is that not all rape allegations are true and that DSK has only been accused not convicted* of it.
*By a competent court of law, as opposed to by a hack on the grounds that he's a liberal and all liberal men are like that.
