Discussion begins with a consideration of security work as a career and the steps required in becoming a security officer. On-the-job requirements, duties, and responsibilities are then reviewed, including appearance, conduct, community relations, and off-duty responsibilities. Subsequent chapters provide detailed training in patrol techniques and procedures, arrests, and law, evidence, and court procedures. A chapter on weapons explains the use of deadly force, revolvers, and nonlethal weapons; while a review of unruly crowds covers types of crowds and mobs, and the development of a crowd into a mob and a mob into a riot. Next, a review of first aid details information on asphyxiation, external heart massage, bleeding, burns, poison, and shock, as well as how to move patients. A final chapter looks at a number of pertinent topics with which the security officer must be familiar: shoplifting and employee theft, burglary and robbery, check frauds, civil disorders, locks, keys, alarms, and dogs. A glossary of terms and an index follow the text; chapter notes and figures are included. Supplementary materials are appended. (Author abstract modified)
