I love jargon. And cop jargon is some of the best. Here’s a Tacoma Police Report from 1946.
07-13-46: Charge of ‘Investigation’: "This Jasper picked up a punk on the stem and took him topside of a flicker. After a bit he gave the boys pork a fumble. The boy didn’t think that was so hot so he took it on the lam and made a beef to the boss. I answered the call and the boy fingered him at 10th and Broadway….the manager has several beefs on this same bird and has the handle of the beefer."
