Also, giving classified information to unauthorized people is a major offense. They threatened me with that offense one time, over texts that I found in a library. If the keys in the database are classified, they can't give them out to cops. FOIA requires that they "segregate" any classified part and give me the rest of what's there, so if they claim that "well, one key isn't classified, but ten or a thousand of them are classified", I bet we can (1) get some keys out, (2) challenge this idea in court. In particular, it should be possible to record the LEAF from a particular chip (whether you own it, or not!) and send it to them in a FOIA request asking for the matching unit key. They clearly can map a LEAF to a key (they do it for cops), and FOIA only requires that you "reasonably describe" the records you want. Given their mapping capability, the LEAF is a reasonable description of the record you want. Good strategy. I still wonder if the decrypted keys are (all) classified, while the encrypted ones aren't. After all, the local cops' magic decoder boxes can strip off that layer of encryption (as, of course, anyone who steals one of those boxes or bribes a local cop). Anyway, I hope the idea works, or at least drives them a bit crazy...
