In his theory of criminal behaviour, Mark Colvin argues that chronic criminals emerge from a developmental process characterized by recurring, erratic episodes of coercion. Colvin's differential coercion theory, which integrates several existing criminological perspectives, lays out a compelling argument that coercive forces create social and psychological dynamics that lead to chronic criminal behaviour. While Colvin's presentation focuses primarily on chronic street criminals, the theory is also applied to exploratory offenders and white collar criminals. In addition, Colvin presents a critique of current crime control measures, which rely heavily on coercion, and offers in their place a comprehensive crime reduction programme based on consistent, non-coercive practices.
