Again, in the criminal context this is a very known standard. It's the standard we use in preliminary inquiries. The balance of probability is not a standard that's used in the criminal context, so it would actually not be what the criminal courts would be familiar with in the context of a criminal proceeding.
As far as the disclosure of the proof goes, we disclose what we're provided by the requesting state. They don't have to give us everything they have, but if we were in possession of something that was actually exculpatory, we would disclose it. On the statement that's been made repeatedly that we hang on to exculpatory evidence, we don't have the whole case, because it's in the foreign state, but if we have something, we're disclosing it. If it's exculpatory, we would certainly be disclosing it.
