Rob Warden is a Chicago legal affairs journalist and co-founder of three organizations dedicated to exonerating the innocent and reforming criminal justice: the Center on Wrongful Convictions at Northwestern University Pritzker School of Law, the National Registry of Exonerations at the University of California-Irvine, and Injustice Watch, a non-partisan, not-for-profit, journalism organization that conducts in-depth research exposing institutional failures that obstruct justice and equality. As an investigative journalist in the 1970s, he began focusing on death penalty cases, which led to a career exposing and publicizing the injustices and misconduct in the legal system. Warden's work was instrumental in the blanket commutation of death row cases in Illinois in 2003 and in the abolition of the Illinois death penalty in 2011.

Warden has done pioneering research work in the field of wrongful convictions that has paved the way for widespread changes in criminal justice practices, including changes in interrogation methods, in eyewitness identification procedures as well as exposing the over-reliance by prosecutors of jailhouse informants and false confessions. Warden is also the author of several books on wrongful conviction cases.

Warden grew up in Carthage, Missouri. He began his journalism career in Missouri in 1960 at the Joplin Globe and went on to work at the Columbia Tribune, the Kalamazoo Gazette, and then in 1965 to the Chicago Daily News, where he was an award-winning Chicago beat reporter and a foreign correspondent until it folded in 1978. At the Daily News, in the mid-1970s, he served as a foreign correspondent based in Beirut, where he and his wife and children were under siege in an ocean-front hotel for several days before they were evacuated.

In 1978, after Warden was asked by a progressive bar association to expand its newsletter, he launched the Chicago Lawyer, which began by reporting on the judicial selection process but soon expanded to reporting on false confessions, police misconduct and judicial incompetence.

In 1982, The Chicago Lawyer published its first of many investigative stories focusing on the “Ford Heights Four” a highly publicized case in which 4 young black men had been convicted by an all-white jury of murder. Warden was first alerted to the gross prosecutorial misconduct which would later be uncovered in that case when he received an unsolicited letter from one of the defendants on death row. It took another 15 years until the wrongfully convicted inmates were to be released and exonerated, after receiving help from students at the Medill School of Journalism at Northwestern who investigated the case for a school assignment.

Warden's reporting was also instrumental in the first DNA-based exoneration in Illinois—that of Gary Dotson who had been falsely convicted of a rape that in fact had not occurred. The Chicago Lawyer focused on many other Death Row cases including Darby Tillis and Perry Cobb, Rolando Cruz and Alex Hernandez, all of whom were later exonerated.

In a law review article, Warden described how he had evolved from a supporter of capital punishment into a crusader for abolition—referring to a thesis advanced by Supreme Court Justice Thurgood Marshall that the average citizen, if fully informed of the realities of capital punishment, would “find it shocking to his conscience and sense of justice.”

In 1999, Warden helped found the Center on Wrongful Convictions, part of the Bluhm Legal Clinic at Northwestern University School of Law. During his tenure there (1999-2014), the Center was instrumental in approximately 25 exonerations of innocent men and women in Illinois.
