UPDATE: 06/30/2011
Wisconsin Traffic Stop Data Collection program has been repealed by 2011 Wisconsin Act 29, effective June 30, 2011. Due to this recently passed legislation, the Wisconsin Office of Justice Assistance (OJA) no longer be accepts traffic stop data submissions. This program represented an enormously successful effort by Wisconsin law enforcement agencies to formally record and report data for individual traffic stops. The duration of the traffic stop data collection program was January 1, 2011 through June 30, 2011.
BACKGROUND
In the past decade, two gubernatorial bodies examined issues described as racial profiling and racial disparities in Wisconsin’s criminal justice system. Both groups recommended collection of racial data when a traffic stop is made as one means to determine the extent to which people of different races may receive different treatment by law enforcement. In support of these recommendations, the Wisconsin Legislature passed 2009 Wisconsin Act 28.
2009 Wisconsin Act 28 required all Wisconsin law enforcement officers to begin collecting and submitting data from traffice stops beginning January 1, 2011, to determine: 1) whether the number of traffic stops between minorities and non-minorities is disproportionate and 2) whether the number of traffic stop searches between minorities and non-minorities is disproportionate.
As required by 2009 Wisconsin Act 28, the Office of Justice Assistance (OJA) promulgated an administrative rule to establish the circumstances under which racial data should be collected by law enforcement, the type of data to be collected, the format in which data is submitted, and the type of analyses OJA will conduct using collected traffic stop data. As part of the rule promulgation process, OJA was assisted by a 17 member Traffic Stop Data Collection Advisory Committee. The committee included representatives from law enforcement (both police and sheriff), community organizations, state agencies and legislators.
2009 Wisconsin Act 28 also required OJA to analyze data and publish a report. The first report was due to the Legislature, the Governor, and the Director of State Courts by July 1, 2012.
The duration of the traffic stop data collection program was January 1, 2011 through June 30, 2011. Because of the short duration of the program and its subsequent repeal, no statewide analysis of traffic stop data is feasible.
