I had the operating director of the Chicago Crime Commission bring before me a list of the outstanding hoodlums, known murderers, murderers which you and I know but can't prove, and there were about one hundred of them, and out of this list I selected twenty-eight men. I put Al Capone at the head and his brother next, and ran down the twenty-eight, every man being really an outlaw. I called them Public Enemies, and so designated them in my letter, sent to the Chief of Police, the Sheriff [and] every law enforcing officer. The purpose is to keep the publicity light shining on Chicago's most prominent, well known and notorious gangsters to the end that they may be under constant observation by the law enforcing authorities and law-abiding citizens.
