Employment of security guards and gaming surveillance officers is expected to grow faster than the average for all occupations through 2012 as concern about crime, vandalism, and terrorism continue to increase the need for security. Demand for guards also will grow as private security firms increasingly perform duties—such as monitoring crowds at airports and providing security in courts—which were formerly handled by government police officers and marshals. Because enlisting the services of a security guard firm is easier and less costly than assuming direct responsibility for hiring, training, and managing a security guard force, job growth is expected to be concentrated among contract security guard agencies. Casinos will continue to hire more surveillance officers as more States legalize gambling and as the number of casinos increases in States where gambling is already legal. Additionally, casino security forces will employ more technically trained personnel as technology becomes increasingly important in thwarting casino cheating and theft.
