In criminology, public-order crime is defined by Siegel (2004) as "crime which involves acts that interfere with the operations of society and the ability of people to function efficiently", i.e., it is behaviour that has been labelled criminal because it is contrary to shared norms, social values, and customs. Robertson (1989:123) maintains a crime is nothing more than "an act that contravenes a law". Generally speaking, deviancy is criminalized when it is too disruptive and has proved uncontrollable through informal sanctions. Public order crime should be distinguished from political crime. In the former, although the identity of the "victim" may be indirect and sometimes diffuse, it is cumulatively the community that suffers, whereas in a political crime, the state perceives itself to be the victim and criminalizes the behaviour it considers threatening. Thus, public order crime includes consensual crime and victimless crime. It asserts the need to use the law to maintain order both in the legal and moral sense. Public order crime is now the preferred term by proponents as against the use of the word "victimless" based on the idea that there are secondary victims (family, friends, acquaintances, and society at large) that can be identified. For example, in cases where a criminal act subverts or undermines the commercial effectiveness of normative business practices, the negative consequences extend beyond those at whom the specific immediate harm was intended. Similarly, in environmental law, there are offences that do not have a direct, immediate, and tangible victim, so crimes go largely unreported and unprosecuted because of the problem of lack of victim awareness. In short, there are no clear, unequivocal definitions of "consensus", "harm", "injury", "offender", and "victim". Such judgments are always informed by contestable, epistemological, moral, and political assumptions (de Haan, 1990: 154). A vice squad is a police division whose focus is stopping public-order crimes like gambling, narcotics, prostitution, and illegal sales of alcohol. England and Wales Note that under English and Welsh law, a "public order offence" is a different category of crime related to disorderly conduct and other breaches of the peace. See the following: Crimes without apparent victims In public order crimes, there are many instances of criminality where a person is accused because he/she has made a personal choice to engage in an activity of which society disapproves, e.g., private recreational drug use. Thus, there is continuing political debate on criminalization versus decriminalization, focusing
