Controversy over auctioning off rifle used in Louisville shooting.

The mayor of Louisville, Craig Greenberg, has said that Kentucky law would make him a criminal if he destroys the assault-style rifle used by a gunman in Monday’s killing of five bank employees in his city. The killer’s rifle was confiscated after police shot him dead, and Kentucky law requires officers to send it to state police officials to sell at auction. Greenberg appealed for Kentucky’s Republican-controlled state legislature to cede responsibility for addressing gun violence to local municipalities.
