The Portland (OR) Police Department is investigating whether or not an officer with the agency is responsible for placing a Blue Line Flag sticker on the rear window of a squad car. If an officer did, in fact, apply the sticker, they may face possible disciplinary action.
According to Willamette Week , adding any visual markings or decals to a city vehicle is not allowed, and the Thin Blue Line flag on the rear window of the patrol car caught on camera at a traffic light qualifies as a violation of policy.
