Here in Germany it has been revealed that the church set up a whole network shuffling around offenders (or sending them away to south america) and muddling traces. It’s even been shown that the former pope knew about such cases. It’s systemic.

Basically it’s a combination of supposed moral authority, intransparency, and mutual cover ups. People are willing to look the other way a lot when they perceive of someone as having a higher mission or great social standing. That includes law enforcement. Think of Donald Trump who’s fraudster-racist-rapist-insurrectionist and yet the MAGA crowd loves him. Maybe celibacy plays into it as well, sexual urges don’t stop just because you don a robe.

Younger people are less and less religious with each generation. So at least from that angle the problem might eventually go away.
