These duties allow police officers to travel around the city and at times outside their jurisdiction to apprehend suspects.
Police officers are able to use firearms and ammunition. They may be armed with a standard duty sidearm, a submachine gun, a riot gun, or a shotgun if a situation calls for such actions.
