But even that could be revealed with the same controls used in courts that handle those issues like unauthorized disclosure of the nuclear missile silo location.

I suppose for the most part one critical function of judges is to override legislation when it appears that injustice would take place. We can't have murderers who say "sorry found some sweet loophole lol". And similarly we can't have abusive cops/prosecutors who want to harass citizens "tell us all your secrets and I'm sure you're guilty of something lol". Judges should be able to make sane tradeoff in the name of justice.
