SUMMARY - Performance Metrics: Arrest Counts or Community Outcomes?

A police department is evaluated by arrest counts, and officers make arrests to meet the numbers that determine their evaluations, and communities bear the consequences of enforcement that serves metrics rather than safety. A city measures policing success by crime rates, and when rates fall the police take credit, and when rates rise they demand more resources, and no one asks whether police activity actually caused the changes being measured. A department is evaluated by response times, and officers race to calls to meet benchmarks, and the quality of what happens after arrival matters less than how quickly they got there. A community survey asks residents whether they feel safe and whether they trust police, and the department that scored poorly last year has not changed but has launched public relations campaigns to improve its numbers. A reforming chief implements new metrics focused on community outcomes - problems solved rather than arrests made, trust built rather than citations issued - and faces resistance from officers accustomed to being measured differently. Performance metrics shape police behaviour. What gets measured gets done. If we measure arrest counts, we get arrests. If we measure community outcomes, we might get something different. The question is what we actually want.

The Case for Outcome-Based Metrics

Advocates argue that traditional metrics incentivize enforcement over effectiveness, that measuring what matters produces what matters, and that community outcomes should replace activity counts.

Traditional metrics incentivize wrong behaviour. When officers are evaluated by arrests, citations, and stops, they produce arrests, citations, and stops - whether or not these activities improve safety. Metrics that count enforcement activity incentivize enforcement activity regardless of outcome.

Community outcomes should be the goal. The purpose of policing is not arrests but safety and wellbeing. Metrics should measure what policing is supposed to produce - crime reduction, fear reduction, community trust, problems solved. Measuring outcomes aligns incentives with purpose.

What gets measured gets done. Officer behaviour follows evaluation criteria. Changing metrics changes behaviour. If we want different policing, we need different ways of measuring policing. Metrics are leverage for change.

From this perspective, police metrics should: focus on outcomes rather than activities; include community perception measures; measure problems solved, not just calls answered; and align evaluation with actual police purpose.

The Case for Activity Metrics

Others argue that outcomes are difficult to measure, that activity metrics provide accountability, and that measuring enforcement has value.

Outcomes are difficult to attribute. Crime rates, community trust, and safety perceptions have many causes. Attributing outcomes to police activity is methodologically difficult. Activity metrics measure what police actually do, not what many factors produce.

Activity metrics provide accountability. Knowing how many stops, arrests, and responses occurred tells us what officers actually did. Without activity tracking, officers could be inactive without accountability. Some activity measurement is necessary.

Enforcement matters. Arrests remove dangerous people from communities. Citations deter violations. Stops disrupt crime. Enforcement activity has value that outcome focus may obscure. Counting enforcement acknowledges its importance.

From this perspective, metrics should: include activity measures for accountability; use outcomes cautiously given attribution challenges; balance enforcement measures with other indicators; and not abandon activity tracking entirely.

The Gaming Question

Will officers game whatever metrics are used?

From one view, all metrics can be gamed. Officers will produce whatever numbers are measured, regardless of underlying reality. Changing metrics changes what is gamed, not whether gaming occurs. Metrics are inherently limited.

From another view, some metrics are harder to game than others. Community surveys are harder to manipulate than arrest counts. Multiple metrics together are harder to game than single metrics. Thoughtful metric design can reduce gaming.

How gaming is addressed shapes metric utility.

The Measurement Question

How do we measure community outcomes?

From one perspective, community surveys, crime rates, fear levels, and trust measures can capture outcomes. While imperfect, these measures provide outcome information that activity metrics lack. Measurement difficulty should not prevent outcome focus.

From another perspective, outcome measures may reflect many factors beyond police activity. Attribution is difficult or impossible. Measuring outcomes police do not control may be unfair and uninformative.

How outcomes are measured shapes whether outcome focus is achievable.

The Resistance Question

Why do officers resist metric changes?

From one view, officers accustomed to evaluation by enforcement activity resist being evaluated differently. Change threatens those who succeeded under old systems. Resistance is predictable response to change, not argument against it.

From another view, officer resistance may reflect legitimate concerns. Outcome metrics may be unfair, may not capture actual work, or may be manipulated by leadership. Resistance may contain information that should be heard.

How resistance is understood shapes response to it.

The Question

When officers chase numbers, what are they really chasing? When crime rates fall and police take credit, what have we learned? If we measure arrests and get arrests, what would we get if we measured safety? When community trust is measured and found low, does measurement change anything? What would policing evaluated by outcomes rather than activity look like? And when what we measure is not what we want, why do we keep measuring it?
