During the last week of October, the Institute for Law Enforcement Administration (ILEA) welcomed law enforcement professionals from across the country to CAIL’s education center in Plano, Texas, for consecutive sessions of their Internal Affairs One and Internal Affairs Two courses. The programs drew officers, supervisors, and investigators eager to strengthen accountability and ethics within their agencies, with participants coming from as far as Alaska.
With instructors representing Grand Prairie, Frisco, and Lexington law enforcement agencies, ILEA’s Internal Affairs programs offer a rare blend of investigative expertise and real-world leadership insight. Together, they connect policy with practice—equipping participants to conduct fair, thorough investigations and lead with integrity.

A Full House for Internal Affairs One: The Investigative Process
Internal Affairs One gathered 40 participants for two days of hands-on training led by Lt. Demoine Clark of the Grand Prairie Police Department. The course equips internal affairs investigators with the knowledge to conduct timely, objective, and thorough administrative investigations—covering complaint procedures, officer-involved shootings, in-custody death investigations, and the use of video evidence in use-of-force reviews.
“Internal Affairs One is geared specifically toward those who maintain compliance with departmental standards, help ensure greater transparency and accountability, and investigate complaints alleging officer wrongdoing,” said Matt Clem, ILEA’s Deputy Director. “It’s the nuts and bolts, the how-tos of doing that work the right way.”
Broadening the Lens with Internal Affairs Two: Professional Standards, Integrity and Ethics
Internal Affairs Two built upon the foundations set during Internal Affairs One with a bigger focus on leadership and integrity. Led by Paul Boyles, a retired lieutenant from the Lexington Police Department and visiting professor at Franciscan University of Steubenville, and Assistant Chief Darren Stevens of the Frisco Police Department, the course examined how command-level leaders can foster a culture of integrity through strong policies, standards, and ethical modeling.
“Internal Affairs Two is geared more toward professional standards, integrity, and accountability,” Clem said. “It’s not just about investigations—it’s about leadership and protecting the nobility of policing as a whole.”
Looking Ahead
The Internal Affairs series remains one of ILEA’s most respected training offerings, helping agencies across the country strengthen investigative integrity and public trust. Future sessions of Internal Affairs One and Two will return to CAIL’s Education Center in Plano in April 2026. Visit ILEA’s program calendar to see full schedule of upcoming programs.
