Misdemeanor crimes; require automatic expungement of.

HB 455 requires Mississippi courts to automatically expunge misdemeanor criminal records in specific cases where a person was arrested but later released without conviction - such as when charges were dismissed, dropped, or the person was found not guilty at trial. This applies to all misdemeanor cases meeting these criteria, directly affecting individuals with dismissed or unresolved misdemeanor charges. The bill updates court procedures to mandate this automatic process and requires law enforcement agencies to report expungements to the Mississippi Justice Information Center. It does not apply to misdemeanor traffic violations or cases involving certain offenses like violent crimes, but focuses solely on clearing records for non-convicted misdemeanor cases.
