i'm in the brainstorming/research part of my story and i want to learn more about the hierarchy and abbreviations used in the police (and law) departments, specifically homicide. for example, "DA Smith" stands for "District Attorney Smith". I want to get all of the abbreviations and status stuff right. could someone point me in the direction of an online glossary or something similar?
i've searched for crime/law abbreviations/terminology, police glossary, and every combination of those on google and wikipedia without luck. :/
