The most glamorous aspect of police work.
The basic responsibility of the police is to fight crime, maintain order, and provide miscellaneous services to the public. Patrol re­mains the basic manner in which police services are delivered to the public.

Criminal investigation is the most glamorous aspect of polic­ing. Most police officers regard detective work as "real" police work. Detective work has a specific mission: apprehending the offender. The quality of work can also be measured in terms of the number of arrests. This contrasts sharply with

patrol duty, which largely in­volves peace-keeping. Good detectives are believed to be able to solve most crimes, so the citizen-victim becomes angry when the police fail to solve the crime he or she suffered from.

The process of investigating a crime involves several different steps performed by at least three different units within the police department: patrol officers, detectives, criminalistics technicians. The two major stages of the investigation process are the preliminary investigation and the follow-up investigation.

The preliminary investigation is normally the responsibility of the patrol officer who is the first to arrive at the scene of the crime. The five major responsibilities include:

1) arresting any suspect or suspects,

2) providing aid to any victims,

3) securing the crime scene to prevent loss of evidence,

4) collecting all relevant physical evidence, and

5) preparing a preliminary report.

Once the responding officer has completed the preliminary investigation, the case is assigned to the detective bureau for the fol­low-up investigation. In all but the smallest departments,the detec­tive unit is separate from the patrol unit. The smallest departments have no separate detective unit. Medium-sized departments have a separate detective unit but detectives handle all types of crime here. Larger departments specialize according to a type of crime (e.g., crimes against person, crimes against property).

Technical specialists in investigation are normally located in a separate administrative unit. They are available upon request to as­sist detectives in the follow-up investigation. Only the larger police departments are able to maintain their own criminalistics special­ists.

The follow-up investigation includes the following steps:

1) interrogation of suspect or suspects, if arrested at the scene of the crime;

2) interview of witnesses;

3) search of the crime scene for physical evidence;

4) modus operandi review to determine, if the crime is similar to others under investigation or resembles crimes committed by known suspects;

5) development of additional information from informants, con­tacts, official records, etc.;

6) preparation of reports.

To obtain information about suspected criminal activity, the police make use of informants. Persons who are either criminals them­selves or who associate with criminals are extremely valuable sources of information. Police officers seek to develop a list of informants.
