The new three-part docuseries '72 Seconds in Rittenhouse Square' reexamines the 2018 stabbing of Sean Schellenger and the acquittal of Michael White for voluntary manslaughter. The filmmakers place the case in the wider context of criminal justice in Philadelphia, touching on Frank Rizzo and the Black Panthers, Daniel Faulkner and Mumia Abu-Jamal and Larry Krasner's controversial reforms.
