This legislation amends the Indian Law Enforcement Reform Act to grant Federal law enforcement authority to qualified Tribal officers. These officers, who perform Federal functions under self-determination contracts, must complete comparable training, pass background investigations, and receive certification from the Office of Justice Services of the Bureau, while their tribes adopt equivalent policies. Once certified, these Tribal officers will be deemed Federal law enforcement officers for key purposes, including protections against assault, eligibility for Federal retirement benefits, and coverage under the Federal Tort Claims Act. The Secretary is directed to establish credentialing procedures and issue guidance within two years, ensuring voluntary participation and allowing for the purchase of service credit for prior years. Additionally, the bill mandates the Attorney General to enhance oversight, coordination, and accountability for all Department of Justice activities concerning public safety in Indian communities. This includes improving training, updating United States Attorney operational plans, and comprehensively evaluating data to ensure a more effective and coordinated approach.
