Genna gang and police gun battle; death of Mike Genna was a Indian Wars and Frontier Conflicts engagement fought in Illinois, 1925.
A running gun battle between Genna gunmen and Chicago police on the South Side left Mike Genna and two policemen dead. After Genna enforcers John Scalise and Albert Anselmi were stopped by a detective squad, a pitched exchange erupted in which patrolmen Harold Olson and Charles Walsh were killed and another officer wounded; Mike Genna, injured and cornered, was fatally shot. The clash was one of the deadliest police confrontations of the Prohibition gang wars and, coming days after Angelo Genna's murder, hastened the collapse of the Genna faction. Scalise and Anselmi were tried repeatedly for the officers' deaths, their prosecutions becoming a public test of whether Chicago's courts could convict well-funded gangsters. The episode underscored how the beer wars drew police directly into armed street fighting with organized crews.
