The policy assumption is that inflexibility is a deterrent because, no matter how or why the rule was broken, the fact that the rule was broken is the basis for the imposition of the penalty. This is intended as a behavior modification strategy: since those at risk know that it may operate unfairly, they may be induced to take even unreasonable steps to avoid breaking the rule. This is a standard policy in rule- and law-based systems around the world on "offenses" as minor as traffic violations to major health and safety legislation for the protection of employees and the environment.
