durkheims functions of crime
boundary maintenance: crime produces a reaction that unites society against the wrongdoer, reminding them of right and wrong
social change: for society to progress, individuals with new ideas must challenge existing norms and values which can be seen as deviant at first
safety valve: provides a harmless way for someone to indulge in desires. eg prostitution releases mens sexual urges without threatening the nuclear family
warning light: deviance indicates that an institution isn't working properly
