Criminal law theory concerns itself with the justification of punishment. Conflicting moral theories of punishment will be held in liberal democracies.

These claims are illustrated by the debate over blackmail prohibition. The best rationale for prohibition is not the moral argument (...) that blackmailers culpably cause harm, but the political argument that blackmailers threaten the state’s claimed monopoly on punishing crime.
