Yes, we did all those things. I'm having trouble with the present tense -- not that I don't think there's still a lot of weeding out to do, but I do think the Church is /beginning/ to understand the scale of the problem and to adopt the right position in the face of it.
It's very hard, because the voices from outside that are pressing on the Church are not the victims, or their families; they are the enemies of the Church, and they don't want to make the Church better, or safer -- they just want it to go away. And frankly, they don't give two shits about the victims, they're just looking for an excuse to attack the institution.
It is essential to its mission that the Church be insular and hard to change from without. A Church that's subject to the whims of society, or its body, or its temporary leaders cannot be effective in preparing the world for conversion through evangelization and the ministry of sacraments. Part of the poverty of response of the Church is normal human corruption, from which one is not vaccinated by ordination. But part of it is also this armor, which is necessary and important to the faith.
None of this is an excuse for the slowness, or should be interpreted as tolerance for corruption, or a way to explain it away. It still all needs to be fixed -- but again, in fixing it, the nature of the Church has to be preserved for the Church to be effective.
