Leveraging video evidence in domestic violence misdemeanour cases: Examination of case dispositions and case length

Law enforcement has used video recording devices (e.g. dash camera, body-worn camera) for more than 40 years, with body-worn cameras emerging in 2005 as a policing tool. However, little is known regarding how video evidence is leveraged in case decision-making and outcomes for domestic violence. Law enforcement may use cameras to enhance evidence collection in domestic violence cases, take statements from victims, witnesses, and offenders, record injuries and damages, and document the administration of risk/injury assessments. Preliminary research has indicated video evidence may have strong evidentiary value in domestic violence cases, however, has rarely controlled for other contributing factors. This study furthers our knowledge by examining how video evidence taken by law enforcement impacts case outcomes and length of time to disposition in a sample of closed, misdemeanour domestic violence cases within a large county in a southwestern state. A random sample of cases (n = 612) with and without video evidence were examined for differences in case disposition and case length. Additional evidentiary factors and case characteristics are considered such as prior criminal charges, victim–offender relationship, presence of non-video evidence, presence of witnesses, and gender of offender. Analyses indicate significant differences, such that cases with video evidence are associated with increased guilty pleas, increased convictions, and less time to closure/final case disposition. Findings have implications for the use of video evidence in strengthening the criminal justice response to domestic violence incidents in combination with other case factors.
