I’ve long been uncomfortable with the idea of registering sex offenders who have served their full sentence. Whatever the courts may have ruled, it doesn’t seem constitutional to impose penalties on criminals beyond what the criminal courts impose.
The Economist points out another problem: existing laws go much further than can be justified on public safety grounds, registering people who are no threat to society. Not only do they needlessly ruin lives, but they also make sex-offender registries ineffective, because it’s impossible to tell who the real dangers are.
