The pattern is clear: homophobic doctrine, arrested emotional development of young Catholic gay boys and adolescents, a high proportion of priests either acting out sexually with boys whose age roughly approximates their own emotional maturity or coping with these pressures through drugs or alcohol. All of which is then compounded by a culture of hierarchy and silence and obedience that impedes airing this clearly, fails to protect children immediately and also allows these screwed up priests to stay in place.
There has been some progress in accountability and openness. But the core elements that made the Catholic Church one of the biggest pedophile conspiracies in the world for decades if not centuries remain: incoherent, irrational and data-resistant doctrines on homosexual orientation and sex in general; a Western culture in which fewer and fewer straight men are prepared to give up sex and love and marriage to serve the church; and a hierarchical structure designed to instill control rather than openness, and perfectly set up to enable cover-ups.
Since the church even now seems incapable of treating child abuse as seriously as the rest of society, it seems to me that increased police involvement is necessary.
