Theodore Postol, an MIT professor who publishes a paper criticizing the missile defense testing program says he’s being shaken down by the Pentagon. The Pentagon is pressuring his bosses to force him to stop disseminating a report that was once public, but has since been declared secret. A Pentagon flack says of the paper, “Just because it is made public doesn’t mean it’s declassified.” You can find more details on the spat between Postol and the Pentagon here. You can find Postol’s letter, which was declared secret, here (PDF).
