Here's a case of Valve coordinating with the FBI, attempting to do what I described: http://gadgets.boingboing.net/2008/11/13/the-job-is-a-lie-val.html http://gadgets.boingboing.net/2008/11/13/the-job-is-a-lie-va.... As for why extradition is not used, the lure is far quicker and much cheaper. The hacker you mention is a perfect example. "The order to extradite McKinnon was approved by the U.K. government in July 2006, but his legal team continued to challenge the order, holding up his transfer." [1] That's over three years ago. That's just when the approval went through mind you. He was indicted in the US in 2002. Also, I'm fairly certain you are incorrect about security clearances (at least for Confidential, Secret, and Top Secret). Even dual citizens have to shred their extra passport and renounce their additional citizenship. The FBI website mentions that for Top Secret, citizenship is verified through investigation: "For a Top Secret security clearance, the background investigation includes additional record checks which can verify citizenship...." [2] If you're working at an intelligence agency like the CIA, Top Secret is pretty much required.
