The FBI combated these & other groups as nodes of a single revolutionary underground dedicated to the violent overthrow of the USA. Burrough's Days of Rage recreates an atmosphere almost unbelievable decades later, conjuring a time of native-born radicals, often nice middle-class kids, smuggling bombs into skyscrapers & detonating them inside the Pentagon & the Capitol, at a Boston courthouse & a Wall Street restaurant. The FBI’s response included the formation of a secret task force, Squad 47, dedicated to hunting the groups down. But Squad 47 itself broke laws in its attempts to bring the revolutionaries to justice. Its efforts ended in fiasco. Drawing on interviews about their experiences with members of the underground & the FBI, Days of Rage is a look into the hearts & minds of homegrown terrorists & federal agents alike, weaving their stories into a secret history of the '70s.
