Actually, it is an academic thesis converted in an awesome brochure that shows us how the Brazilian Civil Police works. A surprising view from inside of its structures by a sociologist that worked as a policeman in State of São Paulo-Brazil for two years, where he has collected interviews with his colleagues and bosses, as well as his own experience on that. It is about police and judicial corruption in Brazil of 80's, just after the 30 years of dictatorial regime and in the first government democratic elected by free suffrage. The changes that were bravely attempted and frustrated because of the "status quo" strength, despite all naive hope of those times. It deserves to be read, absolutely! Herald.
