The Bureau of Investigation (BI) is a law enforcement bureau of California's Office of the Attorney General that provides expert investigative services to assist local, state, and federal agencies in major criminal investigations ranging across the state. The BI can be assigned at the discretion of the State Attorney General, performs investigations on public land for incidents that occur outside of local jurisdictions, or can be requested by local authority for various reasons (e.g. areas that are too small to have local detectives or cross-jurisdiction coordination of major crimes).
