if i learned anything from years of loveline, it's that the "monsters" that molest other children are typically themselves victims of similar abuse. i doubt if this started or ended with the one kid that was caught.
ksuw, you are misreading the article you posted. the pro public authorities woman is not comparing the duggar kid's molestations to raping a sibling at knifepoint. she's doing the exact opposite, she is providing an example of how wide the range of behaviors are that can be classified similarly legally. in her mind, this makes the point that authorities, rather than parents, are best able to choose punishments and treatments that suit the actions of a given juvenile offender.
