Late in April 1977, The Philadelphia Inquirer published a four-part series called The Homicide Files, which told how the Philadelphia homicide detectives were using beatings and other forms of coercion to force "confessions" and other statements from suspects and witnesses. The series, which has since been reprinted in a brochure similar to this one, prompted many citizens to come to The Inquirer with accounts of illegal violence by policemen. Reporters Jonathan Neumann and William K. Marimow, authors of The Homicide Files, decided to expand their investigation beyond the question of homicide interrogations. The result has been a number of vivid, carefully documented case studies of street violence by police officers. This booklet contains a sample of these articles from the late spring and summer of 1977. It also includes The Inquirer's editorials on illegal police violence, as well as news stories on the resolution of the Santiago firebombing case, in which illegal police methods led to the conviction of an innocent man for five murders.
