I think they definitely needed to go in and break up the child sexual abuse which does occur in these groups. Unfortunately, though it is very hard to crack down on polygamy. The same thing happened in the Short Creek raid in 1953. Pretty soon it turned into a PR disaster and they returned the kids to their parents. It's one of the reasons Utah and Arizona haven't tried it since.
I am stil hopeful that something good will come out of it to stop the abuse, but at the same time taking nursing newborns away from their adult mothers for 2 months is just wrong.
There were no nursing newborns taken away from their mothers. All women with infants under age one, regardless of whether the mother was over or under 18, were allowed to remain with their infants.
