Washington D.C. is shown with the caption of February 20th, but flowers are blooming in front of one of the buildings.
Towards the end of the episode, the Naval Intelligence officer engages in a shootout with Kraemer. It is illegal for any branch of the U.S. Military, to engage in police actions, on U.S. soil. He could report what he saw to the local police, and let them handle the situation.
The shooter outside Jim's trailer has a silenced revolver; silencers don't work well with revolvers due to the gap between the cylinder and the frame.
