Longstanding racial tensions between whites and blacks exploded in five days of violence that started on July 27, 1919. On that hot summer day, on a segregated Chicago beach, a group of white men stoned Eugene Williams to death when he crossed the unofficial barrier between the white and black sections of the 29th Street beach. Tensions escalated when a white police officer not only failed to arrest the white man responsible for Williams' death, but arrested a black man instead. Objections by black observers were met with violence by whites. Attacks between white and black mobs erupted swiftly. Because of the rioting, 38 people died (23 African American and 15 white), and another 537 were injured, two-thirds of them African American; one African-American Patrolman John W. Simpson was the only policeman killed in the riot.
Following this win, on July 27, 1979, Ali announced his retirement from boxing. His retirement was short-lived, however; Ali announced his comeback to face Larry Holmes for the WBC belt in an attempt to win the heavyweight championship an unprecedented fourth time. The fight was largely motivated by Ali's need for money.
Centennial Olympic Park was designed as the "town square" of the Olympics, and thousands of spectators had gathered for a late concert and merrymaking. Sometime after midnight, July 27, 1996, Eric Robert Rudolph, a terrorist who would later bomb a lesbian nightclub and two abortion clinics, planted a green backpack containing a fragmentation-laden pipe bomb underneath a bench. Jewell was working as a security guard for the event.
