other-occupancy on reservations maybe by virtue of tribal or individual tenure. There are many churches on reservations; most would occupy tribal land by consent of the federal government or the tribe. BIA agency offices, hospitals, schools, and other facilities usually occupy residual federal parcels within reservations. Many reservations include one or more sections (about 640 acres) of school lands, but those lands typically remain part of the reservation (e.g., Enabling Act of 1910 at Section 20). As a general practice, such lands may sit idle or be grazed by tribal ranchers. Gambling In 1979, the Seminole tribe in Florida opened a high-stakes bingo operation on its reservation in Florida. The state attempted to close the operation down but was stopped in the courts. In the 1980s, the case of California v. Cabazon Band of Mission Indians established the right of reservations to operate other forms of gambling operations. In 1988, Congress passed the Indian Gaming Regulatory Act, which recognized the right of Native American tribes to establish gambling and gaming facilities on their reservations as long as the states in which they are located have some form of legalized gambling. Today, many Native American casinos are used as tourist attractions, including as the basis for hotel and conference facilities, to draw visitors and revenue to reservations. Successful gaming operations on some reservations have greatly increased the economic wealth of some tribes, enabling their investment to improve infrastructure, education, and health for their people. Law enforcement and crime Serious crime on Indian reservations has historically been required (by the 1885 Major Crimes Act, 18 U.S.C. §§1153, 3242, and court decisions) to be investigated by the federal government, usually the Federal Bureau of Investigation, and prosecuted by United States Attorneys of the United States federal judicial district in which the reservation lies. Tribal courts were limited to sentences of one year or less, until on 29 July 2010, the Tribal Law and Order Act was enacted which in some measure reforms the system permitting tribal courts to impose sentences of up to three years provided proceedings are recorded and additional rights are extended to defendants. The Justice Department on 11 January 2010, initiated the Indian Country Law Enforcement Initiative which recognizes problems with law enforcement on Indian reservations and assigns top priority to solving existing problems. The Department of Justice recognizes the unique legal relationship that the United States has with federally
