There was a great to-do some years ago in the city of New York over an ill-omened young person, Duffy by name, who, falling into the bad graces of the police, was most incontinently dragged to headquarters and "mugged" without so much as "By your leave, sir," on the part of the authorities. Having been photographed and measured (in most humiliating fashion) he was turned loose with a gratuitous warning to behave himself in the future and see to it that he did nothing which might gain him even more invidious treatment.
