Last week, tensions between police and citizens again rose to the surface after fatal officer-involved shootings in Tulsa, Oklahoma, and Charlotte, North Carolina.

The shootings, like others before them in the past few years, raised questions over how officers decide to use force during interactions with people they encounter, and seek to arrest.

In the video above, The Daily Signal profiles the Fairfax County Police Department, which serves Virginia’s largest county, to see how officers there try to prevent violent encounters with citizens.

In 2016, a Fairfax County police officer was sentenced to prison for fatally shooting an unarmed man. The incident helped spark the department to reform its training, and become more transparent about the circumstances in which officers use force.
