@matrix Yeah, I thought nothing of it until a few minutes later
The argument could be made that even if he is 17 and it does technically contain sexual content it's not child porn because the intent isn't for sexual gratification but rather comedy instead. It'd actually be pretty easy to argue that as well.
I remember back in the day America's Funniest Home Videos aired a clip of a little boy (probably around 3 years old) running out of the bathroom fully naked clenching a towel in his butt cheeks and screening. I'm sure they blurred the genitals and buttcrack for FCC regulations but even then it was still a naked kid on TV.
There isn't any question as to its intent tho. Just a family video (no sexual intent) and it was funny so presented as comedy to the general public.
It's generally more about the internet when it comes to more abstract concepts in law.
