The Karly Rain Wood Act establishes a federal registration and notification program for individuals convicted of repeat violent felonies, requiring them to register in any jurisdiction where they reside, work, or attend school and to update their information every 90 days for life. The Department of Justice will coordinate with states and Indian tribes to maintain state-level registries, while the FBI will operate a national database and website containing detailed personal information about registered offenders such as names, addresses, vehicle descriptions, and international travel plans. Registered offenders' information will be automatically shared with law enforcement agencies, schools, housing authorities, child protection services, and volunteer organizations working with minors, and jurisdictions must maintain searchable public websites displaying this information with limited exemptions. The bill establishes criminal penalties for failure to register or comply with notification requirements and provides broad liability protection for federal, state, and local government officials acting in good faith to implement the program.
