The depth, nature and extent of the corruption revealed in the NSW police force by the Wood Royal Commission was astounding and appalling. Much of what was learned came from police officers who 'rolled over'. One of the first was Trevor Haken, who now lives in hiding, afraid for his life. But Sympathy for the Devilgoes beyond his evidence to the Commission. It is a startling and revealing expose of a system that was supposed to uphold the truth and protect its citizens, but instead fell into chaos and corruption at its very heart.
