What is the value of an USB stick containing (perhaps) the keys to (perhaps) 371K bitcoins? Around 20 dollars or around 4 million dollars?
If they give him 20 dollars and tell him to go buy a new stick, how can he to argue otherwise? (Without getting into more trouble.)
you'd have to take some precautions if you had obtained that many coins illegally or run the danger of being suspected of illegal activity. Easiest just to put them into a brainwallet and say that brainwallet address is probably the wikileaks donation address you got from wikileaks irc bot when questioned about the whereabout of the 371,076 BTC.
