The United States witnessed increased attention to sex offender management policy at the federal, state and local levels beginning in the 1990s. As a result, laws have been enacted which impose a variety of post-incarceration controls on sex offenders, including but not limited to registration and community notification requirements, civil commitment, global positioning system (GPS) monitoring and tracking, as well as residency restriction. This book provides background information and examines relevant case law, with a particular focus on registration requirements and residency restrictions.
