You say it's the same, but saying it doesn't make it so. Unless someone wants to make it easy to gather the data, it isn't easy. (I just spent 30 minutes trying to find four opera recordings that I made to my own hard drives.) And if you're an agency that deals in classified information, I just cannot believe that you would be dealing in unencrypted data unless you wanted it to be found.

My point is merely that his doing so was only possible in a digital world, as the logistics of stealing 250,000 hard copies makes it quite literally impossible.
