It's a Numbers Game: The Forgotten Zebra Murders: Jack Posobiec on San Francisco’s Terrifying Killing Spree

September 25, 2026·47 min
Episode Description from the Publisher

Ryan Girdusky is joined by Jack Posobiec for a deep dive into one of the most disturbing and controversial true-crime cases of 1970s San Francisco: the Zebra murders. Ryan and Jack retrace the killing spree that terrorized San Francisco, the victims and survivors, the formation of the Zebra Task Force, the controversial police response known as Operation Zebra, and the informant who ultimately helped investigators identify suspects. They also examine the racial and political tensions surrounding San Francisco during the era and discuss why the Zebra murders never became as culturally famous as the Zodiac Killer case.  Plus, Posobiec discusses his book Unhumans: Socialist Revolution, historical political violence, media portrayals of crime, and what he believes Americans can learn from the unrest of the 1960s and 1970s.See omnystudio.com/listener for privacy information.
