From The Philadelphia Public Ledger and Daily Transcript, Tuesday May 27, 1845
Police Distinction--The day policemen of the city, we learn, are hereafter to wear a badge, designating them as the City Police. The badge is of an oblong shape, bearing the city coat of arms, and the words "City Police," and is designed to be worn on the breast of the coat.
These officers constitute, in the largest degree, the preventive police of the city, and it is questionable if, with this mark of designation, they will be as efficient as heretofore. Although they are more entitled, perhaps, to the character of preventive police, they are, nevertheless, a police detective, also, and perhaps in this character the wearing of such a badge will defeat almost entirely all their efforts to detect the rogues that prowl about our depots, and other public places.
