As near as I can tell, it says "forcible fondling." It says he fondled them while they were asleep, and at times when they were awake.
While this is objectionable, it's a long ways from rape or sodomy, which is what is being implied by all the histrionics I am seeing.
Bust his @$$, give him a strong lecture, send him to rehab. What do you want to do beyond that? Put him in Juvvy hall? Let the State raise him for awhile?
Not only does this not improve anything, it would strain the familial relationship even more, not to mention the possibility that the news would get out as to why he's in there and his sisters would then have to face the humiliation from their peers.
It would probably have wrecked his life too. All they learn in Juvenile hall is how to be worse offenders, and the State government can't competently run a comic book collection, let alone juveniles.
When I was about 12, we moved from a good sized City out to the country. When I attended school, I was shocked to see those redneck goatropers grabbing girls boobs or crotches on several occasions. The girls would giggle. Everyone else at the time thought it was funny except for me, but I was a bit of a prude.
I thought it was tasteless and boorish, but I wasn't going to get my @$$ beat for running and tattling to the principle about it. (I was new in that community and I had nothing in common with these hicks.) That it might be a criminal offense never even occurred to me at the time.
I'm wondering what the culture was like in this town where these people come from. Something tells me it is probably similar to that redneck community in which I lived for a few years. It was an odd social environment.
