This bill, known as "Logan's Law," directs the Attorney General to establish a publicly accessible Violent Criminal Offender Database within 180 days of enactment. This database will compile both Federal and State records of individuals with "qualifying convictions," which are defined as offenses punishable by over 180 days imprisonment involving the use or threatened use of physical force, excluding expunged or pardoned convictions. The database must be free, searchable by various criteria including name, address, conviction type, and probation status, and updated at least quarterly. To ensure comprehensive data, the bill mandates that any State receiving funds under the Byrne JAG grant program must submit all relevant qualifying conviction data to the Attorney General. States that fail to comply with this requirement will be penalized by losing their Byrne JAG grant funding, which may then be redirected to local governments within that state. Furthermore, the Attorney General is required to submit a report to Congress detailing current criminal record sharing processes between states and the federal government, identifying any burdens, and providing recommendations to enhance data sharing to protect the public and prevent repeat offenders from receiving lenient sentences due to incomplete information.
