Native American Cultural Resources: Improved Information Could Enhance Agencies' Efforts to Analyze and Respond to Risks of Theft and Damage, Report to the Committee on Indian Affairs, U.S. Senate [open pdf - 7MB]
From the Highlights: "Federal laws prohibit the theft and damage of Native American cultural resources, such as pottery, tools, and sacred objects, on federal and Indian lands. Federal agencies help protect these resources by attempting to prevent theft and damage and by investigating and prosecuting such crimes. These agencies include the Department of Agriculture's U.S. Forest Service; the Department of the Interior's Bureau of Indian Affairs, Bureau of Land Management, U.S. Fish and Wildlife Service, and National Park Service; the U.S. Army Corps of Engineers; and the Tennessee Valley Authority. GAO [Government Accountability Office] was asked to review these agencies' efforts. This report examines (1) approaches selected federal agencies have taken to prevent and detect theft and damage; and (2) factors that have hindered agencies' efforts to prevent, investigate, and prosecute incidents of theft and damage. GAO analyzed data from seven federal agencies, reviewed agency documents, and interviewed agency officials and representatives of Native American tribes."
