I know the Cast Members that were involved with this incident. The guy did get removed from the park, and he was an AP. Was. If I'm not mistaken, this incident happened at closing time, right? So it's not like there was a full queue, so there weren't too many people scarred by his inappropriate activities.
Disgusting none the less though, since aside from the tower there's virtually no way he could've even tried to do it discreetly.
