can't see why you are all getting heated up about nude swimming - I love to do it - and occasionally, there are also friends here while I'm having a swim.
Swimming naked is not illegal!
I do understand, if wives do not want there husbands to be at a pool party with sexual overtones, but Andrew was allready divorced. But even so it wouldn't be illegal.
When I look to the list of Andrews girlfriends, they do not look like he is into nubile girls but goodlooking women.
While I think it showed very poor judgment of Andrew to be present at such parties, considering who he and his family is, it's not illegal.
Till we know more, we cannot condem him for more than poor judgment - everything else is allegation and speculation.
