Connecticut’s “Megan’s Law,” requiring registration of sexual offenders, does not deprive registrants of either a liberty interest or due process. Mere injury to reputation does not deprive one of liberty. Registrants have no due process right to a predeprivation hearing about whether they are currently dangerous because that determination is irrelevant to the statutory scheme. Respondent expressly relied upon a procedural challenge to the statute, and disavowed a substantive due process challenge.
