Contributory factors affecting arrest in domestic and non-domestic assaults

Provides empirical evidence for the first time to suggest that police officers are less apt to arrest in domestic violence cases when directly comparing officers' responses in domestic and non-domestic assaults. Uses a sample of 92,000 police reports in a small midwestern police department of the USA. Supports the premise of disparate treatment for domestic assaults. Finds that injuries were equally likely in domestic and non-domestic assaults; that the impact of weapons is limited. Calls for further research to clarify these issues, e.g., to re-examine officers'definitions of injuries and weapons. Supports findings that officers are more apt to arrest when a victim requests this.
