Techniques of detectives

= Street work =

Detectives have a wide variety of techniques available in conducting investigations. However, the majority of cases are solved by ''interrogation'' of suspects and witnesses, which takes time. In a policeman's career as a uniformed officer and as a detective, a detective develops an intuitive sense of the plausibility of suspect and witness accounts. This intuition may fail at times, but usually is reliable.

Besides interrogations, detectives may rely on a network of informants they have cultivated over the years. Informants often have connections with persons a detective would not be able to approach formally.

In criminal investigations, once a detective has a suspect or suspects in mind, the next step is to produce evidence that will stand up in a court of law. The best way is to obtain a ''confession'' from the suspect, usually in exchange for a infield single plea bargain for a lesser sentence. A detective may lie or otherwise mislead and may psychologically pressure a suspect into confessing, though in the United States suspects may invoke their cartoon strips Miranda rights.

= Court testimony =

Unless a plea bargain forestalls the need for a trial, detectives must testify in court about their investigation.

A famous example came in the murder trial of O. J. Simpson, when Detective Mark Fuhrman of the Los Angeles Police Department testified for the prosecution. Attorney F. Lee Bailey first asked Fuhrman if he had ever used the "n-word" (see nigger_(word)/Nigger). Fuhrman denied this. In court, Bailey produced taped interviews with Fuhrman using this offensive word.
