The Pope was following the confidential orders of the Crimen Sollicitationis to hide the facts, support the priest and deny. The Vatican is still doing that.
You must have missed this explanation of what Crimen Sollicitationis really was meant for in this thread: A Response to Christopher Hitchens' The Great Catholic Coverup (full version with references)
It gets missed on purpose. Some people just don't want facts to get in the way of their Know-Nothing mission of hate.
