SEATTLE (AP) — A 20-year-old Alaska man has pleaded guilty to a federal arson conspiracy charge, acknowledging he set a fire outside a Seattle police precinct during summer protests while others tried to bar a door to keep officers from leaving. Surveillance video showed Desmond David-Pitts piling trash into a sally-port area at the East Precinct and using a lighter to set them ablaze on Aug. 24. Police managed to get outside and extinguish the fire. He faces up to five years in prison when he is sentenced April 27, and he has agreed to pay restitution to the Seattle Police Department for damage to the building.
