The California state senator who represents the Isla Vista community that was ravaged by a mass murder last month has introduced legislation to require law enforcement to check California's gun-purchase database before going out on a welfare check, and provide grants to help police take guns from people who are not allowed to own them.
Police checked on Elliot Rodger, the 22-year-old authorities say killed six people in Isla Vista before killing himself, after his parents alerted them of his violent video rants just a couple weeks before the shooting. The officers did not find evidence that Rodger posed a threat to himself or others.
