Yep. Just like cops killing black men is America’s problem. (Unlike the U.S., however, Pope Francis appears to be actively seeking to remedy the problem.)
A central record tracking system may, indeed, be one of the changes that the pope’s commission recommends and he institutes. The presumption in any organization is that people will follow the rules. Bishops have been charged with making sure that no one reporting to them will continue to abuse kids and the bishops who allowed that to happen in the 90s have been censured and removed from positions of authority. So far, we have claims that there have been five examples of bishops who have apparently violated the rules. (We still have no evidence in four of the cases that the pedophilia came to light before the transfers and we have no timeline for when the transfers occurred.) Setting up a personnel system to monitor that sort of thing takes time and resources.
In the 1980s, the U.S. conference ordered that priests no longer be transferred to parishes if accused of molestation. Out of 280+ diocese, the bishops in fewer than a dozen failed to follow those instructions. Since then, the bishops who ignored those instructions have lost their authority. So, from the perspective of the Vatican, the rules were followed by the vast majority and those who ignored the instructions were punished. It is possible that, with those examples, the Vatican did not see the need to add one more bureaucracy to the church to accomplish what was occurring through normal procedures. If bishops are still dodging their responsibility, then the church very much should set up one more bureau to manage the problem.
