This sounded odd... Pope Francis: '2%' of Catholic clergy are paedophiles'
...in the 90s sitcom Father Ted, there was a joke that was quite similar...
"If theres 100m priests in the world, and 10% of them are paedophiles, thats still only 10m." - Ted Crilly
...and to paraphrase a little, The Pope said much the same...
"If there's 417,553 thousand clergy in the world, and 2% of them are paedophiles, thats still only 8351 thousand." - The Pope
...great comic satire is saying the un-sayable 2 decades before it's acceptable. If 2% is the official Vatican number, then the real percentage is probably higher but still credit to Pope Francis for standing up and admitting this.
