A man who worked in the State Department and his wife have been accused of spying for Cuba for 30 years:

The documents describe the couple’s spying methods changing with the times, beginning with old-fashioned tools of Cold War spying: Morse code messages over a short-wave radio and notes taken on water-soluble paper. By the time they retired from the work in 2007, they were reportedly sending encrypted e-mails from Internet cafes.

The criminal complaint says changing technology also persuaded Gwendolyn Myers to abandon what she considered an easy way of passing information, by changing shopping carts in a grocery store. The document quoted her as saying she would no longer use that tactic. “Now they have cameras, but they didn’t then.”

Store cameras as a deterrent for international spying? That’s a new one. Wonder if I could have added it to proposals and won even more funding?
