On judging and the child abuse scandal

Several people have denounced those who judge the Catholic church for its cover up of child sex abuse by priests. They quote from the Bible, "Judge not that you are not judged".

On child abuse:

Luke chapter 17 (google the Bible reference)
"Jesus said to his disciples: Things that cause people to sin are bound to come, but woe to that person through whom they come. It would be better for him to be thrown into the sea with a millstone tied around his neck than for him to cause one of these little ones to sin. So watch yourselves."

When Jesus says, "little ones", He is speaking of children who are molested.

On Judging:

Here is are some good thoughts by :

Jesus repeatedly taught men to judge rightly, insisting they “judge with righteous judgment” (John 7:24) and He praised a man who “rightly judged” (Luke 7:43). Paul shamed the Corinthian Christians because no one among them was willing to “judge the smallest matters” (1 Cor. 6:2). As the Apostle wrote, “He who is spiritual judges all things” for “we have the mind of Christ” (1 Cor. 2:15-16).

Where did we get the notion that men should never judge? Should child-molesters escape condemnation? Should rapists be free from criticism? Should society refrain from judging those arrested for murder? And why would anyone judge others for judging?
