A Crisis magazine post has the fun title*: The Church Paid 1.8 million and all I got was this lousy report. My sentiments as well. At the risk of sounding anti-intellectual, I think then-Cardinal Ratzinger's diagnosis worth more than these "experts" (since experts in part got us into the crisis given that there was the thinking that pedophiles could be rehabilitated).
* - full disclaimer: I mostly only read the title. I haven't done much of a study of the study.
