Book excerpt: This meticulously researched book uses previously secret official documents to explore the tangled web of relationships between the top echelons of the British establishment, incl Cabinet ministers, senior civil servants, police/military officers and intelligence services with loyalist paramilitaries of the UDA & UVF throughout the 1970s and early 1980s. Covert British Army units, mass sectarian screening, propaganda 'dirty tricks,' arming sectarian killers and a point-blank refusal over the worst two decades of the conflict, to outlaw the largest loyalist killer gang in Northern Ireland. It shows how tactics such as curfew and internment were imposed on the nationalist population in Northern Ireland and how London misled the European Commission over internment's one-sided nature. It focuses particularly on the British Government's refusal to proscribe the UDA for two decades – probably the most serious abdication of the rule of law in the entire conflict. Previously classified documents show a clear pattern of official denial, at the highest levels of government, of the extent and impact of the loyalist assassination campaign.
