We celebrate this milestone; however, we recognize that, as authors, we are responsible for providing readers with essential, up-to-date factual material, policy trends, and changes in law enforcement practices, leadership, emotional intelligence, and mental health. For law enforcement practitioners, Emotional Intelligence (EI) refers to the capacity to effectively and efficiently perceive and process emotions. Emotional Intelligence (EI), by definition, is the ability to motivate and endue oneself despite frustration; to control impulses and postpone satisfaction; to manage feelings and keep trouble from overwhelming the ability to think; to emphasize and to hope—the ability to manage EI abilities with the mindset, personality, and temperament. EI merges two of three mental cognition and the effects of intelligence and emotion.
