This bill, known as the "Promoting Police Leadership Act," seeks to amend the Omnibus Crime Control and Safe Streets Act of 1968 by enhancing the COPS program. Its primary purpose is to improve training for command-level personnel within State, local, and Tribal law enforcement agencies. These personnel are defined as officers responsible for managing, directing, or overseeing law enforcement operations in a specific geographic area. The legislation directs the Attorney General to develop or identify effective training curricula for these command-level officers within 180 days of enactment. The curricula must cover crucial areas such as leadership and strategic thinking , critical incident response and management, risk management, officer wellness, data-driven policing, evidence-based decision making, and building community trust. These training programs are required to include primarily in-person instruction, peer-to-peer learning, and a practical, evidence-based problem-solving component, along with pre- and post-course assessments. Furthermore, the Attorney General must establish a process to certify training programs and courses that incorporate these curricula, ensuring collaboration with educational institutions for continuous improvement. The Attorney General is also required to publish a list of law enforcement agencies whose officers have completed the training and submit annual reports to Congress detailing implementation and effectiveness. Finally, the Comptroller General will conduct a review and report to Congress on the Act's implementation, while explicitly stating that the Act does not preempt State or local authority over law enforcement certification and training standards.
