Ever since legendary British investigative journalist Duncan Campbell told the world in a 1988 magazine article about ECHELON — a massive, automated surveillance dragnet that indiscriminately intercepted phone and Internet data from communications satellites — Western intelligence officials have refused to acknowledge that it existed.
Despite sporadic continuing press reports, people who complained about the program — which, as Campbell disclosed, automatically searched text-based communications using a dictionary of keywords to flag suspicious content — were routinely dismissed as conspiracy theorists.
The only real conspiracy, it turns out, was a conspiracy of silence among the governments that benefited from the program.
