Files recently released to MuckRock include the transcripts of phone calls the Central Intelligence Agency received from Federal Bureau of Investigation and the Washington Metropolitan Police Department in the immediate aftermath of the Watergate arrests.

According to the request, “it is not known what is contained in the tape, but its importance is obvious.”

Records released last week show D.C. Metropolitan Police Department employed a Long Range Acoustic Device during the Women’s March to “direct the crowd flow.” This is the latest evidence of an worrying trend in which police departments are increasingly using the incredibly powerful LRAD to deal with non-violent protests at the risk of causing permanent hearing loss.
