It is the responsibility of the state to ensure the security, the safety of citizens, particularly the most vulnerable. It is the church's responsibility to ensure the safety and security of children, as per Jesus proclamation to let the children come to Him. 
The church has abrogated that responsibility and has not sufficiently reformed itself to ensure the safety of its children. The state, in many instances, has stepped in. Clergy and all citizens should have a legal obligation to inform public authorities of child abuse. If priests prize the "seal" over the injunction of Jesus, let them go to jail. Willingly or otherwise.
