Durkheim suggested that crime was inevitable in society, and a certain amount is necessary for society to function.
TOO LITTLE CRIME - SOCIAL STAGNATION
TOO MUCH CRIME - ANOMIE (confusion over acceptable behaviour)
However, he doesn't quantify the amount of crime required for it to be beneficial to society, how much is too much, how much is too little?
There are three positive functions to crime and deviance"
boundary maintenance
social cohesion
promote change in society
