ODNI's no leak writing policy means I have to chose btwn assigning relevant material & not putting cleared students in untenable positions. — matt blaze (@mattblaze) May 9, 2014

When James Clapper banned intelligence agency employees from discussing or acknowledging the existence of leaked docs (including the Snowden docs), he made life very hard for university professors like Matt Blaze, a security expert whose classes often have students with security clearance.

My own books — which deal with leaks like these — are taught at West Point at a course whose instructors include a member of US Cyber Command. I imagine a rule like this would make future inclusion on the curriculum difficult, if not impossible.
