"After the terrorist attacks of September 11, 2001, U.S. military bases tightened security. The heightened measures included increased ID checks, raising security force numbers, and restricted parking and use of certain roads and previously common areas. The logic behind the increased security may seem apparent, but what is striking is how little analysis has been done on the costs and potential benefits. This project weighs the costs and benefits of security at the Naval Postgraduate School (NPS) in Monterey, California."
