Detectives help solve crimes. They are usually promoted from the role of police officer, and require more leadership, insight, and investigative skills and interests than the daily requirements of an officer on patrol. Because of the complex nature and sometimes morally challenging tasks in detective work, it is crucial that an aspiring police officer or detective have a strong ethical decision making and have demonstrated wisdom in other capacities. The training usually involves the typical police academy, with more coursework in criminal justice.
