I believe her. However, a court of law might not. Sadly= the world we live in.
If-a BIG if- the prostitute story is true, then he is also the kind of man who in his early sixties, and married, fancies his own virility to be so potent that a hotel cleaner on her normal rounds would fall under his spell and willingly fellate him and submit herself to anal intercourse. Then he would be shocked when she asked for money. He, of course would never need to pay for sex, as he is irresistible to women, so he refused her. Then strolled off for lunch with his daughter, knowing he was in the right and that the maid was just one of the many women he has seduced in his time.
So far the examples we have are allegations that he is a harasser (his ex- colleague at the IMF with whom he had a short affair claimed he was insistent and that she had felt cornered), a letch (Air France flight attendant to whom he allegedly remarked 'nice arse') and a man allegedly who forces himself on women (Tristane Banon- attempted rape).
Society clearly thinks this behaviour is acceptable, seeing as he is about to go free AND possibly still have a political career to return to.
