The very efficacy of law enforcement, including its duty to prevent harm, requires agencies to instill a culture that empowers officers to intervene to prevent colleagues from being physically injured, engaging in misconduct, or committing policy and procedural mistakes that can have long-lasting consequences. Shifting officers’ mindset to positive intervention keeps fellow officers safe—physically, emotionally, and professionally—and is essential for public trust. Creating a healthy organization gives officers the confidence and tools to effectively intervene and maintain, or even strengthen, existing relationships. Intervening is one of the most courageous acts an officer can ever do to protect a colleague, themselves, and the future integrity of the law enforcement profession.
