Trial of Crisis Intervention Team (CIT) Mental Health Training for Police Officers

The goal of this clinical trial is to learn the effect, or lack thereof, of the Crisis Intervention Team (CIT) training among police officers. The main questions it aims to answer are: * Whether the 40-hour CIT training improves police officers' verbal crisis de-escalation skills / non-verbal physical behavior * Whether police officers with and without CIT training use different procedural justice and make different disposition-related decisions Participants will: * Receive or not receive CIT training depending on whether they are randomized to the intervention group or the control group. * Participate in three assessments: baseline before the randomization, 3-months post-randomization, and 6-month post-randomization. Researchers will compare police officers who were randomized to the control group with police officers who were randomized to the intervention group to see if receiving the CIT training make differences on the outcome measurements.
