On Denaturalizing Spies
By Dan Cadman on January 19, 2018
On January 16, various news media broke the story of the FBI's arrest of retired Central Intelligence Agency (CIA) officer Jerry Chun Shing Lee the day before, at New York's Kennedy airport. Lee, a naturalized citizen of the United States, was charged with being in unlawful possession of highly classified information derived from his service with the CIA.
According to some accounts, Lee's possession of the material, apparently in the form of comprehensive notes that included real and "operational" names of CIA officers and their foreign agents, as well as actual operations and operational cables, was only the tip of the iceberg. The notes had been provided to China's Ministry of Security to root out those agents, resulting in the death or jailing of at least 20 of them.
