The Seattle Police Department is the law enforcement agency in the city of Seattle, Washington. They provide law and order throughout the city.
During the Invasion of Seattle, some members of the SPD were tasked to intercept suspicious ships that docked in Seattle Harbor. As they moved in to investigate, an MI-24 Hind attacked the police force. As a result, when the Soviets started to overrun the city, they called in the National Guard for backup. Despite the lack of firepower, they still assisted the National Guard evacuate civilians; to the point that some police officers were seen defending a barricade with only revolvers and a shotgun.
After Seattle fell, the SPD was stripped of its duty and was replaced by Soviet military police. Some of its members may have joined guerrillas and resistance fighters throughout the state.
