He has done himself no favours and we all know his lifestyle has had some dubious moments, but ask yourself what you would do if someone accused you of doing something in the distant past and wanted compensation for it ( and whatever she says, I believe Andrew’s accuser is after a payday more than justice)? I suspect that most people have had a one night stand many years ago and if they were introduced to you today, you would have no idea who they were.
How do you prove that you didn’t do it and how do you fund a defence? It certainly wouldn’t be easy. There is also a good chance that your life would be ruined in the process, whether innocent or guilty and especially if you have a high profile.
He might be considered a creep by a lot of people, but he is in a no-win situation. Unlike his accuser.
