I would like to suggest adding a Sheriff's Office as a building. Right now you can train a Deputy Sheriff that is assigned to a Police Station. That is not realistic in the basic structure of law Enforcement in the United States. Sheriff's Offices and Police Departments are two different agency types, with different functions.
Right now, I have to create a Police Station and train all the employees as Deputy Sheriffs to realistically represent a Sheriff's Office. This is time and cost consuming. It would be nice to create a Sheriff's Office and start with Sheriff Deputies.
