City Manager Sylvester Murray has ordered an end to the practice of auctioning weapons impounded by police in San Diego. Murray followed the lead of Police Chief Bill Kolender, who said the guns confiscated in criminal investigations should be taken out of circulation. “We share the conviction that it is not in the best interest of public safety to be returning firearms into a society which is already experiencing crime problems, due in large part to a proliferation of firearms,” Murray said. Auctions of firearms to licensed dealers have added more than $67,000 to city revenues during the last two years. From now on, any firearms that can’t be used by police will be dumped at sea or melted, Murray said.
