Allegation: Man steps outside his home in Southeast D.C. to take some air. He’s obstructing no one, but police officer in a passing patrol car yells at him to move along, arrests him when he declines. Weeks later and a few blocks away, the same officer arrests another man who stepped outside for a smoke (on Christmas Eve) and who was also not obstructing passersby. D.C. Circuit: A D.C. law that authorizes police to arrest (after a warning) people who obstruct pedestrian traffic is not unconstitutional in all its applications.
