Portland: Feds post undercover agents in crowds – Oregon Live

Federal officers have been conducting surveillance of protesters from upper floors of the downtown Mark O. Hatfield Courthouse, analyzing live nightly video footage and posting undercover plainclothes agents among crowds to arrest people on allegations ranging from the shining of lasers at officers to breaking of plywood protecting courthouse doors, federal records reveal.

Federal officers also have shared some of their information with Portland Police officers, who have assisted the federal officers in at least one arrest earlier this month, the documents disclose.
