I think it is Al Capone all over again. They are going to nail Warren Jeffs and the FLDS for tax evasion, or something similar. Modern day witch hunts have a lot more weapons at their disposal and absolutely no one is immune if they are targeted.
Well, taking 400+ children from their parents is certainly a good tactic to get someone to start groveling. Parents will do anything due just about anything to get their children back from a kidnapper. I guess it was at least successful in obtaining the DNA tests on the children.
Now perhaps that tactic has backfired on them to some extent. However, the state has certainly continuing with the threats against the parents. So perhaps it will eventually be effective.
