"Banner said agents did find evidence that suggested Feldman was using a peer-to-peer program called eMule to exchange files with titles suggestive of child pornography." Someone paranoid enough to encrypt 20tb worth of hard drives is dumb enough to use eMule to transfer highly illicit material? Unless of course it was emule over something like Tor or I2P, which I wasn't even aware worked. If that was the case, I'm more curious about how they tracked him to his actual IP through those services, than the actual drives. Was it the same way they got that anonymous hacker a few months back, where they camped outside his place and sniffed his wifi for the packets to start flying?
