Other major professions that would be affected by the elimination of crime are the U.S. Armed Forces. Many Marines, Army, Air Force and Navy personnel reside in Chester County, including one of the authors, Marine Corporal Cianci. In fact, there is an Army National Guard base located in the center of West Chester, Pa. Without crime there would be a decline in the capacity of the armed forces. The loss or decrease of these crime dependent jobs would damage the local economy. The education system is another entity that is affected by crime. Chester county colleges such as West Chester University, Penn State Great Valley, and Immaculata University are well known for their criminal justice programs. Without crime, classrooms would be oregon lineman empty and teachers would be unemployed. Universities would be forced to downsize. The criminal justice curriculum would cease to produce revenues. Universities that base their curriculum strictly on law would be disseminated. Finally, the reader must consider how manufacturing plants affect the local economy. Law enforcement officers drive specifically manufactured vehicles that aid their crime fighting abilities and even make it possible. These vehicles are equipped with lights, sirens, and custom made seats. Ford, General Motors, and Chrysler are the three major U.S. car manufactures responsible for law enforcement vehicle assembly (Police Cars). If crime were to be eliminated the manufacturing segment of the economy would be tarnished. Decreased manufacturing would lead to a decrease in the Gross Domestic Product. The principles of economics determine that manufacturing facilities harbored in the United States provide a greater economic benefit than imported vehicles.
