I would like to add in the law enforcement context, which is an answer I wanted to provide to an earlier question as well, that there's another layer of complexity in the law enforcement when it's information that's obtained by virtue of a search warrant, because then you're getting into judicial authorization.
When law enforcement bodies obtain information pursuant to judicial authorization, they report back to the issuing authority, so it's out of their hands to destroy or handle that information in any way. It belongs to the judge who issued the search warrant. There's a different set of parameters in the law enforcement context.
