If it’s Los Gatos, CA it is ultra lib.
If the LG city council (or any other gov’t) has the votes, they can pass anything they want. If the citizens don’t like it, they can protest or vote them out. If it is unconstitutional(fed or state), it can be challenged in the courts, which could take years.
But........ don’t hold your breath. The 2a is one of the least defended rights we have. SCOTUS ruled against DC in the Heller case. Pre-Heller, it was impossible to purchase a handgun. Post-Heller, it’s now only nearly impossible.
