This will get messy. Everyone will start pulling at this database. Can they send men to prison on account the information needed to exonerate them is classified, even if the person requesting the data is the same person under surveillance?
Even if it could be applied without regard to whether the defendant objected, it has been gutted in recent decades by our radical right-wing Supreme Court, who think illegally-obtained evidence is just dandy so long as excluding it from court proceedings wouldn't actually change the government's behavior in collecting it.
Data cannot 'deny' something. Ask your coffee cup what the weather is and all you get back is silence :)
