Josh was a young teen when this occurred. The father reported it to the police. Since then Josh has had no further known issues.
Its pretty silly to label a young teen a pedo for being curious about girls. What he did was wrong and illegal. But it in no way reflects on his behavior as an adult. He was a curious and horny teen with hormones running wild. Just like any other horny young boy who gets his first erection. Their dick gets hard when the wind blows.
He lived in a huge family. He would have been caught if he had gone into their bedrooms and continued touching the girls. AFAIK theres been no further incidents since it was reported to the police.
TLC must have known.
