Legal Child Sexual abuse in America?

Today as I sit not able to tear my thoughts away from the fact that somewhere in this country of ours there is a child that may be in need of help. Help to get away from what he or she may have to endure from their sexual abuser. Lets take a moment and think about this. The U.S. deems Crimes Against Children a Capital crime, thus bringing with it a Capital punishment. That said, why are the Polygamist able to hide behind the Cloth and still operate within our Country. The Catholic Priest accused and convicted are not able to. We are coming down pretty hard on them, and for good reason. Please stay tuned, because I think I may have become a self proclaimed Investigative Reporter by Fiat alone.
