The Maintenance of Silence (1985)

On November 18 1982, a 22-year old Aucklander, Neil Roberts, daubed a washroom wall with the graffiti slogan: ‘WE HAVE MAINTAINED A SILENCE CLOSELY RESEMBLING STUPIDITY’. He then placed a bomb outside the State Security Computer Centre at Whanganui where files are kept on all citizens. The bomb blew him to pieces.
