Local considerations

Investigative considerations in Portsmouth.

Working in a smaller community

At about 1,439 residents per square mile, Portsmouth mixes a compact center with lower-density neighborhoods. Field work in Portsmouth is planned around a handful of main routes and a small number of places where a subject is likely to be, which keeps sessions short and costs predictable.

Highways and regional travel

Interstate 95 and U.S. Route 4 run through or near Portsmouth. Highway access means a routine can take someone well outside town in minutes. Mobile surveillance is staffed and timed with that in mind, and locate work follows the same corridors.

Near a state line

Communities near Portsmouth include places in Maine. Licensing and privacy laws change at the state line, so work that crosses it is coordinated with a detective properly licensed for each jurisdiction.
