Police Investigation

Show Summary Details


Chapter 6 begins by reviewing the state of knowledge on crime investigation, since it is the least researched topic in policing studies. The remainder of the chapter is divided into three parts. First, the powers of investigators, as exercised through a system of judicial warrants, are scrutinized. Second, a typology of the nine basic kinds of criminal inquiries is developed. It is based on a distinction between investigations where the crime is acknowledged but its perpetrator(s) unknown and investigations where a potential suspect is identified but the criminal nature of his or her activities unclear. Third, empirical research findings on homicide investigation are presented. These highlight that the majority of homicide investigations are solved within 12 hours and that forensic science plays almost no part in clearing up homicide cases. Finally, the previous findings are discussed in relation to a theory of criminal investigation viewing it as an information process.
