I grew up near annother Amish community in Missouri and my family often hired an Amish man for odd jobs who a few years after I left home, went to prison for molesting underage granddaughters. I and my family were shocked.
I wonder if the strong patriarchal nature of Amish families has something to do with this sort of behavior.
I don't disagree with the prosecutor for the original plea agreement. Young Amish men can be very nieve and unsophisticated. I think he's probably right, prison would probably be the end of them. If the local Amish community really did punish them harshly, Amish are rather well practiced at punishing those that break community rules, I don't think the prosecutor was wrong. But it looks like the young men didn't take the prosecutor seriously.
