Feeley and Simon see actuarial justice as a new form of surveillance. It uses actuarial analysis (statistical calculations of risk) to predict the likelihood of people offending
Unlike disciplinary power that focuses on groups and individuals, it is not interested in rehabilitating offenders, but simply in preventing them from offending.
Individuals can be profiled using the defender risk factors, giving each person a risk score. Anyone scoring a bother given level can be stopped or questioned etc
According to Lyon, the purpose of this social sorting is to categorise people, so they can be treated differently according to the level of risk they pose
However, offender profiles are often compiled using official statistics, which show certain groups as more likely to offend. Profiling leads to police targeting these groups, who are those more likely to be caught and convicted.
