Republican proposal would shield info of some gun owners KGO) -- In California, new legislation has been announced to protect the privacy of citizens who choose to legally own a firearm. It comes after a journalist last month published the names and addresses of thousands of New Yorkers with gun permits. California already has an assault weapons ban and a 10-round capacity limit on ammunition. The Brady Campaign considers California as having the toughest gun control laws in the country. Still, the Newtown, Connecticut massacre is prompting lawmakers to propose measures that go further than President Obama's package of reforms. State Sen. Kevin DeLeon, D-Los Angeles, wants California to start doing background checks on people before they buy ammunition and require a permit to proceed with the sale.
