Well, I got alittle bit different take on this. Maybe it's because I was a child of a single parent whose father took off and my mother got no help from him. I also am the husband of a woman with a chikd from a previous marrage whose ex does not pay his child support regularly.
I don't have a problem with the kid paying child support. I very seriously doubt if the 15 year old had to be tied down and actually forced to have sex with her. At 15 you should know the potential consequences of sex, a baby being one of them. If he didn't then blaime the situation on his parents for not at least having a few convesations with him.
50 bucks child support is nothing. Tell the 16 year old to get a job and support his child. Take the rest of the money he is earning and get his baby out of the abusers home, if thats where the baby is. I have absolutely zero tolerance for ANYONE who tried to get out of supporting thier child. And yes that includes a 16 year old. If I found out that someone I knew was hiding out to avoid paying child support, I would narc that person out as quick as I could find a phone and the number to the state attorny general's office. I have more sympathy for the fly that hit my windshield on the way to work this morning.
As far as the girl being charged with a crime, thats a whole different issue. Unless in court it is shown that she physically forced herself on him, If I was a juror I would have to say not guilty.
You could think of government workers like teenagers. You pay them an allowance, but do you get any work out them? They eat the food, put their feet on the furniture and complain loudly whenever they are unhappy.
