Warren PD Targets Domestic Violence With Focused Deterrence Strategy

Warren Police Department launched a focused deterrence programme in 2025 to cut domestic violence recidivism. Police1.com reports the approach includes lethality assessments and offender monitoring.

Warren Police Department Tackles Domestic Violence With Data-Driven Deterrence Model

At the start of 2025, Warren Police Department undertook a systematic review of its crime data after a new commissioner took office, according to police1.com. The analysis revealed that the overwhelming majority of violent crime in the city was rooted in domestic violence incidents.

That finding prompted the department to re-examine its response model and seek outside expertise. Partnerships were established with the 37th District Court, Turning Point Macomb and Wayne State University to develop a more comprehensive approach to the problem.

Existing Framework and Its Gaps

Warren PD's baseline response already aligned with recognised law enforcement best practices. Officers dispatched to domestic violence calls are required to file a report and make an arrest where probable cause exists. Victims receive a rights card listing local resources, including information on the detective bureau, filing charges and obtaining a personal protection order.

Cases are then passed to the detective bureau for follow-up investigation. Where probable cause is established, detectives submit a warrant request to the prosecutor's office. When an arrest is made over a weekend, the offender is issued an interim bond and notified of a court date at a later stage. Under the previous model, the period between arrest and court appearance ranged from two to three weeks to several months.

The Focused Deterrence Model

Research into how other agencies had reduced violent crime led Warren PD to focused deterrence — a strategy that targets specific criminal behaviour by combining the credible threat of consequences with incentives for offenders to change. The model was first deployed by Boston Police Department in Operation Ceasefire, which targeted youth gun violence and was associated with a reported 63 per cent reduction in youth homicides.

High Point, North Carolina subsequently applied the model to domestic violence with notable results. High Point's demographics, population size and crime profile are comparable to Warren's. In the five years before implementation, High Point recorded 17 domestic homicides; in the seven years following, that figure fell to three. Domestic calls for service also dropped by an estimated 20 per cent. Academic research further indicated that more than half of domestic violence offenders had also committed violent crimes against people outside the household — suggesting that targeting this group could produce broader reductions in violent crime overall.

Three Enhancements Added to the Warren Response

Warren PD identified three specific additions to its existing model.

1. Domestic Violence Lethality Assessments

Officers now complete a standardised questionnaire with victims to gauge the severity of abuse and identify high-risk cases. One risk factor assessed is strangulation: research cited by the department indicates that victims of non-fatal strangulation face a seven times greater risk of homicide. The assessments also help victims recognise the seriousness of their situation and encourage them to seek assistance. As an additional benefit, police1.com notes that the process has generated criminal intelligence — several drug and firearm seizures have since originated from calls initially classified as routine domestic incidents.

2. Active Monitoring of Domestic Violence Offenders

A core principle of focused deterrence is that swift and certain consequences, paired with access to support services, can influence offender decision-making. Warren PD implemented a systematic monitoring process using an online spreadsheet to track all domestic violence cases, recording offender names, lethality assessment scores and arrest status. Priority was given to severe assaults, repeat offenders and individuals identified as high risk through the assessment tool.

Once arrested, detectives meet with offenders directly to communicate that their conduct is unacceptable and will remain under close scrutiny. The department also identified local counselling services to offer offenders a pathway toward behavioural change — reflecting the dual-track structure central to the focused deterrence approach.

3. Court and Community Coordination

The partnership with the 37th District Court was designed to address the lengthy gap between arrest and court appearance that had characterised the previous model. Tighter coordination with judicial partners aims to ensure that accountability follows more swiftly from arrest — reinforcing the message delivered to offenders at the point of detention.

Broader Implications

Warren PD's approach reflects a growing body of evidence that focused deterrence, when adapted to domestic violence contexts, can produce measurable reductions in repeat offending and related serious crime. The department's decision to embed academic and community partners from the outset distinguishes the programme from enforcement-only responses and positions it as a model other mid-sized police departments may look to replicate.

Results from Warren's implementation had not yet been published in full at the time of reporting, but police1.com indicates the programme was operational and generating early indicators — including the drug and firearm seizures linked to lethality assessment conversations — that suggest the expanded framework is functioning as intended.
