This document discusses ethical and legal issues around using anonymous sources in journalism. It outlines three types of anonymity - background, deep background, and off the record - and stresses the importance of always negotiating the terms of anonymity. Legally, the 1972 Branzburg v. Hayes Supreme Court decision found no right to protect sources, though some protections may exist under a three-part balancing test. Privacy laws also place some restrictions on newsgathering to prevent intrusion, publicizing of private facts, or false light portrayals. Journalists must balance First Amendment protections with ethical standards around verifying information and the motivations of anonymous sources.
