Whats a detective?
In some cases, it’s a rank. In others, it’s a job description. For example, the San Francisco PD doesn’t have a title “detective.” Plainclothes officers assigned to investigate crimes are called “Inspectors” in that department. The NYPD, on the other hand, has three grades of detectives and two of Inspector. (Detective 3rd Grade, Detective 2nd, Detective 1st, Deputy Inspector and Inspector.) Basically, a detective is a police officer assigned to investigate crimes, identify the criminals, apprehend them, and shepard the case through the courts.
