In contrast, there is the argument for restraining legal powers, to allow citizen freedom make victimless personal choices that may or may not be perceived as morally wrong. Preventative law, such as sex offender registries and anti-social behavior orders, blurs the distinction between criminal and civil law because victimless crime is typically difficult to categorize and criminalize. This is problematic because it causes a distortion of traditional procedures of the criminal and civil of aspects of law by enabling confusion and procedural interchangeability.
