The Director can spend money to purchase evidence or information, or to offer a reward, in the investigation of a crime. This is subject to the availability of funds. This authority may be delegated in writing to supervisory criminal investigators within the Office of Law Enforcement Services in the BIA. The Director must develop policies and procedures for the expenditure, control, and audit of these funds before their use.

Each local law enforcement program must establish its own uniform requirements for patrol and detention personnel. Uniformed BIA police officers may be paid an annual uniform allowance not to exceed $400. Local programs may provide uniforms and related equipment to officers in lieu of this payment. All law enforcement officers must also have their official identification on their person at all times when performing law enforcement duties. Uniforms, when worn, will be plainly distinguishable from the uniforms of any non-law enforcement personnel working on the reservation.

Law enforcement commissions will only be issued by the Bureau of Indian Affairs to persons occupying positions as full-time officers. Bureau of Indian Affairs funded or commissioned criminal investigators will not be responsible for supervising or managing any patrol, detention, or other uniformed police programs.
