Upstanding citizen in Salem (30+ years in same neighborhood) went down the street when multiple police showed up. Citizen stands across street taking one-to two pictures. Told to stop, or be arrested. Citizen stopped, put camera in pocket and asked to speak with supervisor who showed up momentarily. Sgt. (supervisor) agrees that citizen can take pictures. Citizen takes camera out of pocket for 1-2 more shots.
Citizen later "detained" while Sgt. investigated "interception of communications" law violation, based (assumed) on Cpl.'s statement who 5-minutes earlier asked if camera recorded video.
