California Gov. Gavin Newsom on Friday signed a law that will make the state the first to allow employers, co-workers and teachers to seek gun violence restraining orders against other people.
The bill was vetoed twice by former Gov. Jerry Brown, a Democrat, and goes beyond a measure that he signed allowing only law enforcement officers and immediate family members to ask judges to temporarily take away people's guns when they are deemed a danger to themselves or others.
Newsom, also a Democrat, signed a companion bill allowing the gun violence restraining orders to last up to five years, although the gun owners could petition to end those restrictions earlier.
The new pieces of legislation are among 15 gun-related laws that Newsom approved this year as the state strengthens what the Brady Campaign to Prevent Gun Violence calls the nation's toughest restrictions.
"California has outperformed the rest of the nation, because of our gun safety laws, in reducing the gun murder rate substantially compared to the national reduction," Newsom said as he signed the measures, surrounded by state lawmakers. "No state does it as well or comprehensively as the state of California, and we still have a long way to go."
Between 1993 and 2017, there was a 62% decline in the gun murder rate in California, nearly double the national rate, he said.
Brady Campaign spokeswoman Amanda Wilcox, who lost her 19-year-old daughter to gun violence in 2001, said that California's laws are already so strict that the latest bills amount to "tweaks to policies already in place, ways to improve implementation" of existing limits.
Seventeen states and the District of Columbia have laws similar to California's existing restraining order law. But the state's new law, that takes effect on Jan. 1, will be one step broader.
"With school and workplace shootings on the rise, it's common sense to give the people we see every day the power to intervene and prevent tragedies," said the bill's author, Assemblyman Phil Ting, a San Francisco Democrat. The existing law has mostly been used by police officers, but Ting said the expansion should allow more awareness and more opportunity for others to act.
"These are the people that often see the signs earlier, can see the signs faster," he added. "They’re around individuals more often, and unfortunately, this is also where the shootings are happening."
The new California law will require co-workers requesting the orders to have "substantial and regular interactions" with gun owners to seek the orders. Co-workers and school employees must get approval from their employers or school administrators before seeking them. People seeking the orders will have to file sworn statements specifying their reasons for doing so.
The measure was opposed by gun owners' rights groups and the American Civil Liberties Union. The ACLU said the bill "poses a significant threat to civil liberties" because orders can be sought before gun owners have an opportunity to contest the requests.
Those allowed to request orders under the new law may "lack the relationship or skills required to make an appropriate assessment," the ACLU said.
Ting cited a recent study finding that gun restraining order laws may have helped prevent 21 mass shootings, though the UC Davis researchers cautioned that "it is impossible to know whether violence would have occurred."
The companion bill was authored by Democratic Assemblywoman Jacqui Irwin, who cited last year's slaying of a dozen people at the Borderline Bar and Grill in her Southern California community of Thousand Oaks.
