More than two dozen journalism school deans and professors, independent editors, journalists and authors have sent an open letter to major media editors, criticizing media coverage of Iraq and warning that "this is no time for relying solely on official sources and their supporters." Signers of the letter include: retired New York Times columnist Tom Wicker; former New York Times reporter William Serrin; Ben Bagdikian, former dean of the Graduate School of Journalism at University of California at Berkeley; author Studs Terkel; independent journalist and filmmaker Barbara Koeppell; and author Ralph Nader.
