Malcolm Gladwell examines the trial of John Forrest Parker for the murder of Elizabeth Sennett, highlighting how medical evidence and timing cast serious doubt on whether Parker actually inflicted the fatal stab wounds, and pointing instead toward her husband, Reverend Charles Sennett. The episode then traces how Alabama's judicial override system allowed a judge to impose the death penalty against a jury's recommendation of life without parole, and how the state later abolished override without correcting past cases, leaving Parker on death row despite the system's acknowledged flaws.
This short episode introduces a special seven-episode Revisionist History series titled "The Alabama Murders." Using the 2003 Northeast blackout as an analogy for a "failure cascade," the host frames a decades-long Alabama murder case as a moral and legal cascade involving a woman killed in her home, a charismatic preacher, disputed jury and judicial decisions, long imprisonment, lethal injection, and far‑reaching harm. Interview clips hint at themes of religious culture, judicial power, the death penalty, and how a justice system meant to respond to suffering can instead amplify it.
