Proposal to ban 'ghost guns' in San Diego The ordinance would make the gun kits illegal. and last updated 2021-07-28 20:32:01-04 SAN DIEGO (KGTV) -- Thereâs a new effort to get ghost guns off the street. A proposal by San Diego City Councilmember Marni Von Wilpert would make it illegal for unserialized gun kits to be sold in San Diego. That would include sales both online and in stores. Police say the guns are a big problem, making it harder for them to do their jobs. âItâs difficult for officers to go to scene where someoneâs been shot⦠and find out it was a ghost gun that was so easy to obtain,â said San Diego Police Chief David Nisleit earlier this month.
