I don't give a shit about legally. This is what he told the public at large.That's not what his statement means. Also keep in mind he had just been publicly outed as gay by the accusation and was trying to deal with that at the same time. Apologizing is the standard tactic for these sorts of things. It is not an admission of anything. Indeed, many jurisdictions including Ontario have an apologies act for the very point of encouraging apologies without exposing you to liability.
Why would you even entertain the notion that although you don't remember the event, that it could have happened? That was the statement he issued. He was drinking a lot back then and that he didn't remember, but if it did happen he was sorry.
If it did happen?
So, if he was a pedophile he apologizes. Yeah, NO!!!!!
The statement from any sane person who does not have any tendencies to sexually assault a child would be simply, "I vehemently deny what I'm being accused of, because I am not a pedophile."
