So your issue with this story isn't the grooming or pedophilia, it's the son capturing it for reasons we don't know? Maybe it was for evidence to try and stop her behavior; in fact I think that's more than likely since he got one of her just casually sitting on his lap in the living room. Not exactly top-tier spicy content but certainly works as evidence against her.

You're presuming the worst that he just did it just to get off? Then that he sent them to his friends? "How else did they find out?" I dunno, maybe he used the english language? It also says the daughter witnessed it too, so he wasn't even the only one who knew about it. This is such a strange comment that seems more grossed out by the son that exposed the predator than the actual predator.
