Peace Officers commissioned by the Alabama Coushatta Indian Tribe have the authority to:

The correct choice highlights that Peace Officers commissioned by the Alabama Coushatta Indian Tribe have the authority to make arrests without warrants. This power is rooted in their status as law enforcement officers operating under the jurisdiction of their tribal government. Many tribal governments are sovereign entities and can grant their law enforcement officers specific powers that may differ from those of local, state, or federal officers.

This ability to make warrantless arrests aligns with general principles of law enforcement where officers can act without a warrant if there is probable cause to believe that a crime is being committed or has been committed. This is particularly relevant in tribal jurisdictions, where the laws may incorporate unique provisions tailored to the needs of the tribe.

In contrast, the other options do not accurately reflect the scope of authority granted to these officers. While they may enforce certain federal laws, their primary jurisdiction and authority lie within their own tribal laws and regulations rather than exclusively federal laws. Their responsibilities are not limited to tribal lands, as they may have authority over certain areas beyond those borders depending on tribal law. Additionally, conducting investigations typically involves oversight and is not done in a manner devoid of supervision, as proper protocol usually necessitates some level of accountability.
