Cooperation between public and private police in providing security for the Olympics was facilitated by the Olympic Law Enforcement Coordinating Council, which was composed of representatives of all units responsible for or having a stake in security. Planning was the responsibility of second-echelon officers from these same units, with 16 interagency subcommittees responsible for implementation and operations. A total of 11,000 persons were trained for private security operations. Trainers and training coordinators were trained to provide the instruction. The trainees were students, averaging 19.3 years old and most having no prior security experience. All candidates were interviewed and screened. Two classes, each with 100 students, were conducted simultaneously over 2-day periods 6 days a week. Each class was taught by a team of two instructors. Instruction was provided in accreditation management, emergency operations procedures, communications equipment, report writing, equipment and uniform care, data procedures, and power of arrest. Testing of students at the conclusion of the course produced few failures. Training effectiveness can be measured by the absence of any serious security incident and a reduction in the overall crime rate in areas surrounding Olympic activities. Nine notes are listed.
