This report provides the findings of two skills conversion research teams on the placement of displaced aerospace and defense engineers, scientists, and technicians in the fields of security systems and criminal justice. The teams, located in Philadelphia and San Jose, concluded independently that a minimum of 2,000 positions could be created in these fields from 1972 through 1975. Positions would be available both in private enterprise and government agencies in the areas of program planning, police and court work, and correctional systems. This study was conducted for the U.S. Department of Labor. (Author/AG)
