Survivors of Operation Spectrum—the alleged Marxist conspiracy—speak up in this volume. For many of them, this is the first time that they cast their minds back to 1987 and try to make sense of the incident. What they did in that period was meaningful and totally legitimate. Their families and friends share the same view. The detainees were subjected to ill-treatment, humiliation, and manipulated television appearances. Under duress, and threatened with indefinite imprisonment without trial, they had to make statutory declarations against their will. It is hoped that with this publication, Singaporeans will know what actually happened and decide for themselves if there was a national security threat that necessitated the mounting of Operation Spectrum.
