I am guessing that the involvement at a federal level has something to do with the fact that the Pope is finally defrocking bishops found guilty of sexual misconduct. The era of covering up for these abuses is coming to an end. No matter what anyone might think, the Pope and the Catholic Church still has a LOT of power. And now that they are bending to public opinions and outcries the potential for other governments to actually be able to fight and win is much higher.
Once federal governments get started cracking down on this it is only a matter of time before they go on to other, smaller, fish to fry. It may be a while yet but we are on the right track, finally!
