In most US states, priests are mostly exempt from having to testify in providing confessions of any crime, although the priest-penitent privilege can be challenged in certain cases such as child sex abuse. Under Roman Catholic law, a priest who discloses what is revealed to him in Confession may be subject to excommunication.
I vote no unless the person who confessed is actively committing the crime or has expressed intention of doing it again.
