What agency is responsible for developing policy and procedures for Military Criminal Investigative Organizations related to adult sexual assault investigations?

The Naval Criminal Investigative Service (NCIS) is the agency responsible for developing policy and procedures specifically for military criminal investigative organizations concerning adult sexual assault investigations. NCIS plays a crucial role in the military's approach to handling such sensitive and serious crimes. Their responsibilities include ensuring proper protocols are followed, which align with the broader goals of the Sexual Assault Prevention and Response Program.

The emphasis on NCIS is due to their specialized expertise and authority in conducting criminal investigations within the Navy and Marine Corps. This close operational involvement means they are better equipped to respond to the unique aspects of sexual assault cases in a military context and to implement best practices that inform training and response strategies.

In contrast, while the Office of the Deputy Assistant Secretary of Defense and the Department of the Navy have roles in overarching policy-making and oversight for military standards and practices, they do not specifically manage the day-to-day investigative procedures that NCIS handles. The Military Police Corps primarily focuses on law enforcement duties and may work alongside NCIS but does not lead the development of investigative policies for sexual assault. This delineation clarifies why the responsibility rests with NCIS rather than any other agency.
