No it has not.
The bishops in the United States have adopted an "everyone is a molester" policy.
Every volunteer who may be in the vicinity of children must have criminal background checks, every employee regardless of who they may contact must have a criminal background check. Every employee and volunteer must attend "Virtus" training programs. And the children... God save us, the children have their innocence destroyed in a classroom setting so um, their innocence won't be destroyed. It's a nightmare, everyone from parish priest to kindergartner has to pretty much walk around constantly on guard that everyone around them is a child molester.
The program came out in 2004, my wife and I won't let our children be involved, we weighed the risks and decided the cure was worse than the disease. It's not so much zero tolerance as it's zero sense.
