What's the difference, Iscool? The state can't force God to testify at the point of a gun?
Incidentally, the law in this country protects the confidentiality of discussions with all ministers of religion, not just Catholic priests.
Also incidentally, a priest is typically not going to let someone who confesses a heinous crime off the hook just for saying he's sorry. There's this little matter of penance, which may well involve a visit to the police station in addition to 5 Hail Marys.
A fundamentalist wouldn't do that...
