“…Constables had some legal obligations to keep the peace and prevent crime, but these responsibilities were rarely enforced and in practice policing was largely motivated by rewards paid to informers for successful prosecutions. Many of these rewards were defined in national legislation in response to concerns about particular crimes, especially crimes against property; but others were offered by private actors such as Prosecution Associations; or sought by the police themselves in return for catching thieves and returning stolen goods (Beattie, 1986, 2001; Landau, 1999; Paley, 1989; Phillips, 1989). These practices encouraged the emergence of a small-class of what Clive Emsley terms ‘entrepreneurial’ police who earned a living from their role, but were found almost exclusively in London where the concentration of population led to more crime and hence greater opportunity to secure rewards (Emsley, 1996, p. 20).…”
