Yesterday the Senate had two votes related to the Foreign Intelligence Surveillance Act and President Bush devoted a portion of his State of the Union Address to a call for an extension of his surveillance authority and for immunity for telecommunications companies who cooperated with his administration in surveillance operations. But questions surrounding surveillance are far more pervasive than even this controversy suggests. No Comment puts six questions to Christopher Slobogin, a law professor at the University of Florida widely regarded for his work in the area. Professor Slobogin’s new book, Privacy at Risk: The New Government Surveillance and the Fourth Amendment, has just been published by the University of Chicago Press.
