The Minneapolis Domestic Violence Experiment (MDVE) evaluated the effectiveness of various police responses to domestic violence calls in Minneapolis, Minnesota. This experiment was implemented during 1981-82 by Lawrence W. Sherman, Director of Research at the Police Foundation, and by the Minneapolis Police Department with funding support from the National Institute of Justice. Among a pool of domestic violence offenders for whom there was probable cause to make an arrest, the study design called for officers to randomly select one third of the offenders for arrest, one third would be counseled and one third would be separated from their domestic partner.
