A U.S. air marshal alerted the press of a decision by TSA to cut marshals from flights known to be at risk for hijacking. The TSA fired him for “disclosing sensitive information”–a TSA regulation. He appealed based on the fact that he hadn’t broken any law and he had a right to alert the public of safety issues under a U.S. whistleblower law. The U.S. Supreme Court agreed. However, this doesn’t mean that we will be alerted in the future, because Congress or even the President by executive order could make such revelations illegal. See, Dept. Homeland Security v. MacLean, No. 13–894. Argued November 4, 2014—Decided January 21, 2015.
