As a special police officer, you provide safety and security services for an assigned area or company. You may work as an auxiliary police officer for the police force to provide support for full-time officers, or you may work in a fire police or company police unit. Hospitals, university campuses, and museums often rely on special police officers to keep the peace. Your job duties are similar to those of other law enforcement officials. You may direct traffic, make traffic stops, conduct investigations and make arrests. Depending where you work, you may or may not carry a firearm.
