The proposed Traffic Stops Statistics Study Act of 2001—Title II of Senate Bill 19 of the 107th Congress—was the third consecutive legislative proposal aimed at addressing the perceived problems of racial profiling and police abuse in the detention of minority motorists for allegedly unjustifiable reasons. The measure followed Senate Bill 821 from the 106th Congress and House Bill 118 from the 105th Congress. This study looks at the purpose of these bills, explores the reasons supporters believe that federal policy mandating law enforcement agencies to collect racial data on motorists stopped and detained is needed, and examines a number of public policy questions that a Traffic Stops Statistics Study Act might raise.
