I assume UP is talking about Jonny Saville, Garry Glitter and Rolf Harris. I don't know enough of the details about cover ups there but it would, at least in Saville's case, be the NHS as well as hospitals covered up for him as well. From what I do know about that stuff though it is not really comparable to the Catholic Church.
Despite the Louis CK video (which I think is fucking funny) I don't think the Church's problems with child molestation and cover ups really is about fucking children. I think it is more the tension between the Church being its own authority and not succumbing to temporal authority. The same things that resulted in conflict between Henry II of England and the Thomas Beckett - "Which cracker will rid me of this turbulent priest!"
It is why the Catholic Church has been a bastion of thieves, murderers and looters for the past 1000 years or more.
