High Quality Content by WIKIPEDIA articles! 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 that 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.
