They’ve banned high-capacity magazines and cracked down on assault weapons. They’ve made it so Californians have to pass a background check to purchase a gun and ammunition. They’ve prohibited buyers from having ammo or “ghost” gun parts shipped directly to their homes.

When it comes to gun laws, California’s legislators have passed some of the most stringent regulations in the country, checking off nearly every box on national gun control advocates’ wishlist.

A mass shooting early Sunday that left six dead and 12 wounded just a block from the Capitol — the very building where these laws were enacted — immediately prompted new calls for legislation to curb gun violence, from California elected officials and gun-control advocates across the nation.

“The scourge of gun violence continues to be a crisis in our country, and we must resolve to bring an end to this carnage,” Gov. Gavin Newsom, who’s already signed 15 gun-control laws, said Sunday in a prepared statement.

Paredes said lawmakers are gliding over the real issues that drive gun violence.

“Is it mental? Economic? Medical? What is it? They won’t go there. Their knee-jerk reaction is to go after guns,” Paredes said.
