The mission of the Office of Justice Services (OJS) is to uphold Tribal sovereignty and provide for the safety of Indian communities by ensuring the protection of life and property, enforcing laws, maintaining justice and order, and by ensuring that sentenced American Indian offenders are confined in safe, secure, and humane environments. Ensuring public safety and justice is arguably the most fundamental of government services provided in Tribal communities.
