Rather than putting the mother on social assistance the father should have to come up with the cash or trade his labour for that support bestowed on the people.
I think that you would find a lot of support for that idea... However, it doesn't necessarily substitute for the value that a responsible/concerned parent represents in developing the direction and individuality of the kid.
In the end, that's what I was getting at earlier. The young offender that has now taken 2 lives has destroyed 2 families and he is coming out unscathed... I no longer give a rats-a$$ about that kid - ultimately he's broken beyond repair - my concern lies for his next victim(s) and the destruction that he will cause those families.
