How much has the Catholic church spent on cild abuse cases?

The molestation and rape of children by priests in America has resulted in more than $3.3 billion of settlements over the past 15 years, $1.3 billion of that in California. The total is likely to increase as more states follow California and Delaware in relaxing the statute of limitations on these crimes, most of which were reported long after they happened. For an organisation with revenues of $170 billion that might seem manageable. But settlements are made by individual dioceses and religious orders, whose pockets are less deep than those of the church as a whole.
