Re point 3, the bullying and tattling that was encouraged meant that the Temple Police flourished. The Roman Curia under JPII relished all the delations that arrived in Rome. And what is worse, those accused were never told from whom the delations came.
A fairly recent victim of the Temple Police is of course Bishop Bill Morrison formerly bishop of Toowoomba. (Bishop Geoffrey Robinson would have been too if he had not retired early).
They are in good company of course, given that Jesus was the first victim of the Temple Police of His time.
