I just don't understand why someone who works on a children's show would think its a good idea to hang out with sixteen or seventeen year old boys? Even if its not a sex thing.
Big Brother/Big Sister sort of thing? Mentoring? I can think of several legit reasons.
Working in that type of environment, I would find a way to donate my time that wouldn't have the potential to put me in a compromising position.
Honestly, I don't know whether or not the man is guilty (and I'm glad I don't have to make that judgement). But if he was spending time with these boys alone it will be impossible to disprove these charges.
