I was surprised to find out that California already has laws in place that enable it to confiscate weapons from the mentally ill in addition to convicted felons. Unfortunately, the State does not apparently have the funds to actually go out and seize the weapons.
From the LA Times:
SACRAMENTO — California authorities are empowered to seize weapons owned by convicted felons and people with mental illness, but staff shortages and funding cuts have left a backlog of more than 19,700 people to disarm, a law enforcement official said Tuesday.
Those gun owners have roughly 39,000 firearms, said Stephen Lindley, chief of the Bureau of Firearms for the state Department of Justice, testifying at a joint legislative hearing. His office lacks enough staff to confiscate all the weapons, which are recorded in the state’s Armed Prohibited Persons database, he said.
The gun owners typically acquired the firearms legally, before being convicted of a felony or diagnosed with mental illness. Each year, the state investigates and seizes the guns of about 2,000 people on the Armed Prohibited Persons list, Lindley said, but each year about 3,000 names are added to the list.
“Despite our best efforts, the bureau does not have the funding or resources to keep up with this annual influx,” he told the 15 assembled lawmakers.
