ILJ has conducted an evaluation of grantees programs awarded to law enforcement and prosecutors' offices as part of the grants to encourage arrest policies from the Violence Against Women Office (VAWO), USDOJ. Detailed study of 20 sites resulted in process evaluations for a limited subset. More than 200 domestic violence victims participated, after giving written informed consent. Summary statistics, sampled data, and victim interviews were analyzed and assessments of case processing and program conditions were developed. Most grants resulted in greater cooperation among criminal justice agencies and victims services organizations. Specialized domestic violence resources among police and prosecutors improved evidence collection, increased batterer apprehension, and strengthened reporting. Further research could assess effects of greater monitoring of probation conditions and aggressive protection order enforcement.
