Establishes a law enforcement mutual aid region comprised of nine Kansas City Metropolitan area counties: Kansas border counties (Johnson, Leavenworth, Miami, Wyandotte) and Missouri border counties (Platte, Clay, Ray, Jackson, Cass)

Permits all law enforcement officers in the mutual aid region to respond to lawful requests for assistance in critical incidents (those risking serious injury or death) or noncritical incidents (those requiring specialized equipment, training, or resources) in any other jurisdiction within the region

Grants on-scene incident commanders authority to request assistance in critical incidents and maintain command until transferred to another person; requires chief executives to request assistance in noncritical incidents

Provides that officers making arrests outside their home state must deliver offenders to the first commissioned officer in the jurisdiction where the arrest was made

Deems responding officers as employees of the requesting agency for liability and workers' compensation purposes; grants qualified immunity to members acting in good faith and in an objectively reasonable manner

Requires the Missouri Department of Public Safety director to certify that Kansas has enacted similar legislation before the section becomes effective, contingent on unanimous written affirmation from the governor, house speaker, and senate president pro tempore
