The world was glued to the television on April 19, 1995, when the Oklahoma City bombing—America’s deadliest act of homegrown terrorism—claimed the lives of 168 people, 19 of them children. And many remember the 1993 siege of a religious compound in Waco, Texas, 51 days that saw the deaths of more than 80 Branch Davidians, including their leader, David Koresh. (If you weren’t aware of it in real time, you’ll likely have watched Waco, 2018’s fictional screen adaptation.) What’s less known are the underlying connections between the two events: the Oklahoma City bomber Timothy McVeigh, for instance, claimed to be acting in revenge for the Waco fiasco. This 11-episode podcast, hosted by journalist Leah Sottile, traces the history of America’s conspiracy movements—how they’ve intertwined and the violence they’ve helped spawn—and casts today’s far-right QAnon group as a natural, if terrifying, continuation of the many movements that came before it. —J.V.
