Dual arrest decisions in domestic violence cases: The influence of departmental policies

Dual arrests in family violence cases have increased following passage of proarrest laws. This study examined the relationship between officers' perceptions of their departmental policies and arrest outcomes. Each officer was given 1 of 6 hypothetical scripts that varied as to whether the wife only was injured or the wife and husband were injured. They were their asked what action they would take. Results indicate that officers who believed that their department would support arrest of both parties are more likely to arrest both parties. Officers who perceived that their department encouraged arrest of the primary aggressor only are more likely to arrest the husband only. When both parties were injured, officers were likely to arrest both. Experienced officers were more likely than novice officers to use dual arrest. Implications for the importance of primary aggressor language are discussed.
