Exceptional Clearances, "Real" Cases of Intimate Partner Violence, and Mandatory Arrest Laws.

This study examined the extent to which cases of intimate partner violence were cleared by arrest, remained open, or closed by exceptional clearance. Incident and state-level factors associated with each outcome were examined for incidents submitted to the National Incident-Based Reporting System (NIBRS) from 2000 to 2009. Using the 10 years of data, comprising 5,481 jurisdictions in 36 states and the District of Columbia, findings show exceptional clearance is more likely to occur in residences, incidents of lower severity, and with same-sex couples, while being less likely in states with preferred and mandatory arrest laws.

Same-Sex Couples and the Police: A 10-Year Study of Arrest and Dual Arrest Rates in Responding to Incidents of Intimate Partner Violence.

Despite concern, little research has been conducted on whether victims in same-sex relationships receive disparate treatment from law enforcement. Utilizing 2000 through 2009 National Incident-Based Reporting System data, the authors examine the police response to incidents involving same-sex and heterosexual couples in 2,625,753 cases across 5,481 jurisdictions in 36 states and Washington, D.C.

A 10-Year Study of the Impact of Intimate Partner Violence Primary Aggressor Laws on Single and Dual Arrest.

The adoption of arrest as the preferred response in incidents of intimate partner violence has generally been welcomed, but it has not come without unintended consequences. Foremost among these has been an increase in dual arrest, the situation where both parties to an incident are arrested. To address this concern, many states have enacted primary aggressor laws which mandate that officers determine who is the primary aggressor in the incident.

The Impact of Primary Aggressor Laws on Single Versus Dual Arrest in Incidents of Intimate Partner Violence.

To combat the concern that mandatory arrest laws have resulted in officers unjustly arresting victims, states have enacted primary aggressor laws. Examining 3,078 incidents of intimate partner violence reported to the police in 25 jurisdictions in four states, the authors assess the impact of primary aggressor laws on the likelihood of both single and dual arrest. While dual arrests were more than twice as likely in a state without a primary arrest statute, an arrest was nearly a third less likely in a state with such a statute.

The impact of offenders leaving the scene on the police decision to arrest in cases of intimate partner violence.

In this article, the authors examine an issue that has not been studied in depth by prior research: the impact that fleeing the scene has on the likelihood of arrest in intimate partner violence cases. Using police data obtained from 25 police departments in four states, and controlling for a variety of incident, offender, victim, and jurisdictional characteristics, the authors find that an offender who flees the scene of the incident is more than 5 times less likely to be arrested than one who remains at the scene. The policy implications of the findings are discussed.

Severity of injury and the decision to arrest in cases of intimate partner violence.

From a victim's physical health perspective, at the centre of any case of intimate partner violence (IPV) is the degree of trauma imparted on that victim by the offender. Yet, the implementations of state-level 'Mandatory Arrest' and 'Preferred Arrest' laws encourage arrests decisions in cases of IPV typically without regard to the level of trauma severity found in each case. And, despite these well-meaning implementations and the gravity of their consequences, the importance of evaluating trauma severity in victims of IPV remains largely overlooked.

Unraveling the relative contributions of his, her, and their drinking to the likelihood of arrest in intimate partner violence cases.

The nexus between substance abuse and intimate partner violence has been studied in depth. The interrelationship between drinking, intimate partner violence, and an officer's decision to make an arrest has not received as much attention. The issue is complicated by the fact that either or both of the involved parties may have been drinking and the effects may vary depending on who has been drinking.

Offender-victim body mass ratio and the decision to arrest in cases of intimate partner violence.

As a result of the growing trend toward criminalisation of cases of domestic violence, there has been a great increase in the number of jurisdictions in the United States that have implemented 'pro-arrest' and 'mandatory arrest' laws. One of the objectives of this legislation is to encourage arrest when there is probable cause to believe that an assault has occurred. Along with the increase in the overall rate of arrest for intimate partner violence there has been a dramatic increase in the arrest of both the parties involved in an incident.

A comparison of the police response to heterosexual versus same-sex intimate partner violence.

It has been argued that the police do not respond to domestic calls involving same-sex couples in the same manner as they respond to calls involving heterosexual couples. A major problem facing researchers examining the police response to cases involving same-sex couples has been the lack of adequately sized samples. In this article, the authors utilize the 2000 National Incident Based Reporting System database, which contains 176,488 intimate partner assaults and intimidation incidents reported to 2,819 police departments in 19 states.
