The Stop Predator Dumping Act establishes rules to prevent states from concentrating conditionally released sexually violent predators in specific neighborhoods or communities. The bill requires covered states to implement a placement framework that maintains at least a 10-mile distance between released individuals, distributes placements sequentially across county subdivisions to prevent concentration, and caps placements at 25 percent in any single district within large counties. The Department of Justice must conduct a study within 60 days to examine how these individuals are currently distributed geographically, identify communities bearing disproportionate burdens such as rural areas, and issue best practices recommendations within one year. States that adopt these equitable distribution practices are eligible to receive federal grants to help implement and monitor the new policies. The bill authorizes whatever funding is necessary for the Department of Justice to administer the grant program, though no specific dollar amount is specified.
