This is now the top story at forbes.com.
It was also pointed out by Mike Caldwell in the Press section that "FBI" encodes as "324" on a telephone pad. Does that not seem like too much fanfare for the FBI?
I can't imagine someone at the FBI doing the transfers slowly in 324 units. It would be madness and the supervising officer would surely wonder why it's taking so long.
Also, why would the FBI want to tag their transfers?
