“Is it secret? Is it safe?” For those who’ve never seen the 1976 film Marathon Man, that’s what the fugitive Nazi war criminal played by Sir Laurence Olivier asks Dustin Hoffman while he’s sticking a pointy dental probe into Hoffman’s exposed cavity. Ouch. Excellent movie, though. Cinema trivia notwithstanding, these are pertinent questions federal agencies need to ask when it comes to information under their control.
