Tanenbaum is the author of thirty-two books—twenty-nine novels and three nonfiction books: Badge of the Assassin, the true account of his investigation and trials of self-proclaimed members of the Black Liberation Army who assassinated two NYPD police officers; The Piano Teacher: The True Story of a Psychotic Killer; and Echoes of My Soul, the true story of a shocking double murder that resulted in the DA exonerating an innocent man while searching for the real killer. The case was cited by Supreme Court Chief Justice Earl Warren in the famous Miranda decision.

He served as Deputy Chief counsel for the Congressional Committee investigation into the assassinations of President John F. Kennedy and the Rev. Dr. Martin Luther King, Jr. He also served two terms as mayor of Beverly Hills and taught Advanced Criminal Procedure for four years at Boalt Hall School of Law, University of California, Berkeley, and has conducted continuing legal education (CLE) seminars for practicing lawyers in California, New York, and Pennsylvania.
