Why is the United States, the rich and wonderful land of freedom and opportunity, also the most violent country in the Western world? In the last book of his life, almost an ideal testament, the author moves between private memories and collective memory to get to the heart of the rampant phenomenon of gun proliferation in America and the bloody massacres that have resulted from it. Silent witnesses of the crime scene, the photographs portray the sites of the massacres in all their ordinariness: black and white shots, with no human presence, because nothing human remains there anymore.
