from msnbc.com: Former Bush National Security Agency Director Michael Hayden learned the hard way Thursday afternoon that you never know who’s listening. Hayden was on an Amtrak Acela train reportedly attempting to give an anonymous quote to a newspaper reporter disparaging the Obama administration’s handling of the fallout from revelations that the NSA spied on U.S. allies, when a former liberal activist named Tom Matzzie began live-tweeting Hayden’s phone conversation.
