Catholic Church and the Child Sex Scandal in Ireland

It appears that the Catholic Church in Ireland is going to conduct a full investigation into the child sexual abuse perpetrated by the clergy in Ireland. The enquiry will be carried out by priests led by an Archbishop (I couldn't believe it either). The clergy in Ireland are a small gossipy elite (Father Ted is funny because it's so true) and if there was a cover up I would bet my debt that priests who didn't know what was going on were the exceptions and very few. What are the Garda, who should be carrying out this investigation doing. Isn't it a criminal offence in Ireland to conceal knowledge of a criminal offence ? Let's see the whole fucking lot of them in court to answer to man, who I think might be a harsher judge in this instance than their God.
