At the Rocky Flats plant outside Denver — where every American plutonium trigger was made — the movement put its bodies on the railroad. Beginning in April 1978, blockaders occupied the tracks into the plant for over a year; among the hundreds arrested were Daniel Ellsberg and the poet Allen Ginsberg, whose "Plutonian Ode" was written the night before his arrest. The trials became forums on the bomb, with defendants arguing necessity to Colorado juries.
The campaign built the coalition of pacifists, downwinders, and eventually plant workers whose pressure — joined in 1989 by an unprecedented FBI raid on the plant itself for environmental crimes — closed Rocky Flats for good: a rare case in which the protesters' indictment of a facility was ratified by the government's own.
