Another big disclosure about concealing child abuse by priests.

FOX's Steve Taylor reports:

Pennsylvania's Attorney General says that two Roman Catholic bishops covered-up sexual abuse allegations against more than 50 priests over a 40-year period in the Altoona-Johnstown Diocese, where legal authorities found a secret archive detailing the abuse and concealment.

No criminal charges are being filed because some of the abusers have died, the statute of limitations expired and some victims are too traumatized to testify, according to the Attorney General. The current bishop is not accused of any wrongdoing.
