This document summarizes two classic studies on labelling theory and the social construction of crime and deviance:
1. William Chambliss's (1973) study of two delinquent gangs, the "Saints" and "Roughnecks", found that the middle-class "Saints" engaged in more serious delinquent acts but were not viewed as criminals by police due to their social class.
2. Jock Young's (1971) study of hippie marijuana users in London found that negative police perceptions of hippies as "dirty" and "drug addicts" caused the hippies to unite and develop more deviant norms in response to feeling socially excluded and criminalized.
