The surveillance activities of the Federal Bureau of Investigation in Portland and other American cities earlier this year is reminiscent of FBI-CIA-NSA efforts to disrupt anti-Vietnam protest groups in the 1960s and 1970s.  In 2021, FBI agents, dressed in plainclothes,  were embedded in Portland's racial justice protests.  Agents alerted local police to potential arrests. The Department of Justice and its Office of the Inspector General must investigate these activities closely because they replicate the illegal activities of the FBI's counterintelligence program during the Cold War.The FBI has been conducting domestic surveillance operations since its inception in the 1920s, marking nearly a hundred years of violating the First Amendment of the Constitution.
