Did you miss my big, big disclaimer? “excepting the potential for abuse of this precedent”.
Only in a perfect scenario would there be no abuse, so it's nonsensical to ignore it. The reality is how bad will the abuse have to be before this program is deemed a failure.
Given that the parents and family have proven themselves to be bad influences and unfit guardians, why would we WANT to continue exposing the kids to their influence?
There was no due process to kidnap the kids. Part of the parents sentence was not loss of custody. If you look at history the state has been a much more terrible guardian.
