Local considerations

Investigative considerations in Washington.

Residential neighborhoods

Washington is largely residential, at about 3,732 residents per square mile. Cul-de-sacs, school traffic and neighbors who know each other's cars all affect how lawful observation is planned. Shorter, well-timed sessions based on known schedules usually work better than long open-ended watches.

Long commutes and out-of-town routines

Workers in Washington spend about 34 minutes getting to work on average (ACS 2020-2024). When someone's day happens mostly elsewhere, an investigation may begin in Washington but continue across the region, which affects timing, staffing and cost.
