Public and extending retention requirements for certain firearm permit data classification

This bill changes how certain firearm permit data is handled in Minnesota. It makes specific information public, including permit revocations/suspensions and details when a permit holder dies by firearm suicide or during police use of force. Sheriffs must delete most permit records annually but must keep records of denied/revoked permits (for six years), voided permits due to legal prohibitions, and death-related cases (for six years after the event). These changes directly affect permit applicants, current permit holders, and law enforcement agencies managing firearm permit records. The bill focuses on data classification and retention rules, not new firearm restrictions.
