This is the fourth in a series of studies evaluating the perceptions of U.S. Department of Agriculture Forest Service (USFS) law enforcement personnel regarding their profession. The ultimate goals of the work are threefold. First, the Law Enforcement and Investigations (LEI) studies serve as a followup to a previous qualitative study to learn more about crime and violence in national forests and grasslands and the impacts on recreation visitation and management of those national forests. Second, the LEI studies serve as a followup to a previous qualitative study testing the key characteristics of success in law enforcement, measuring opinions about recreation visitor and public safety, and evaluating impacts to natural resources. Third, the LEI studies serve to provide Credibility Through Accountability/Performance Accountability System data for LEI.
