History

Historical Context

On October 1963, Mafia soldier Joseph Valachi testified before Senator John L. McClellan’s Senate subcommittee, confirming the Mafia’s existence and describing its Cosa Nostra hierarchy. The hearings prompted the Justice Department to create an Organized Crime Strike Force to improve informant cooperation. Decades later, prosecutors’ dismissal of tips from mob informant Joseph Ippolito in the 1994 O.J. Simpson murder case shows the reform’s limits.
