"Does anyone really think that if this is happening in Norway and the Netherlands that is not really happening in in far worse numbers in countries with greater social and economic problems? Places where there are practically public markets for child sex trade?"

Using the RC Church's own logic, one would expect the behaviour to occur at least in the same statistical number in most areas(though one could suspect in greater numbers in some of the areas noted. That alone would justify the logic behind a belief that there are much more than reported yet....and it is likely the RC church knows of some of these, if not all that have not been made public. Thus the call to come clean and open the books, since many of these would be considered crimes in most if not all societies.
