Patrol officer activity by single- versus double-crewed status: The call-related output of one-officer and two-officer patrol units

Purpose

Longstanding debates in policing regard the optimal method of patrolling the community. One question that often gets raised is if patrol officers should be deployed in single-crewed (i.e., one-officer) or double-crewed (i.e., two-officer) units? As part of the present research, we empirically examine the call-related output of patrol units by crewed status in Oakland, California.

Methods

Drawing upon calls for service data from the Oakland Police Department, we retrospectively reconstructed the patrol environment to assess the call-related output of single- versus double-crewed units. We also explored potential variation in the output of double-crewed units as a function of pairing characteristics (e.g., regularly partnered versus not regularly partnered).

Results

Our results revealed that single- and double-crewed units handled similar numbers of calls for service, although sometimes of potentially different types, in similar amounts of time. Our results also revealed that the output of double-crewed units was similar regardless of the pairing characteristics examined.

Conclusions

Whereas many police agencies deploy their patrol officers in single-crewed units, other police agencies deploy their patrol officers in double-crewed units. Overall, we find limited variation among the output of patrol units by crewed status. We discuss our results in the context of research and practice.
