From American Libraries Online:
A federal appeals judge has criticized the FBI’s permanent ban on speech in terrorism investigations—the gag provision allowed by National Security Letters (NSLs) authorized by the USA Patriot Act—as probably unconstitutional in the light of recent congressional amendments to the law. Judge Richard Cardamone of the U.S. Court of Appeals for the Second Circuit in New York City made the comments as the court ruled May 23 on two challenges filed by the American Civil Liberties Union, one of them involving librarians in a Connecticut library consortium who received a demand for patron records through an NSL.
