NPR: In California, officials are ramping up a unique program that identifies and seizes guns from people who are prohibited from keeping them. Under state law, a legally registered gun owner loses the right to own a firearm when he or she is convicted of a crime or becomes mentally ill.
Last year, state agents seized nearly 2,000 firearms, but implementing the gun seizure program is a painstaking job. In a recent operation, a caravan of four unmarked trucks traversed the bedroom communities of San Francisco's East Bay. The trucks carry nine state agents wearing bulletproof vests and armed with .40-caliber Glock pistols and Tasers. They'll spend the next six hours looking for illegal guns, explains Special Agent Kisu Yo of the California Department of Justice.
