San Bernadino is a county in California, and also a city located in that county. The city has a population over 200K, making it the 17th largest city in California and 100th largest city in the United States. Two shootings happened there in the past two years in spite of the fact that California has some of the most restrictive firearms laws in the US (including some new onerous regulations regarding purchase and sale of ammunition).
According to Wikipedia, Syed Rizwan Farook and Tashfeen Malik, a married couple living in the city of Redlands, targeted a San Bernardino County Department of Public Health training event and Christmas party of about 80 employees in a rented banquet room. Farook was a U.S.-born citizen of Pakistani descent, who worked as a health department employee. Malik was a Pakistani-born lawful permanent resident of the United States.
According to public information, the couple had no legitimate ties to any known terrorist organization outside or inside the United States. They had amassed a large quantity of weapons and bomb making supplies. The couple left three pipe bombs at the scene which failed to explode, so the 14 fatalities and 22 wounded were the result of rifle and handgun fire. Both Farook and Malik were killed in shootouts with police.
Cedric Anderson, 53 year old estranged husband of Karen Elizabeth Smith, also 53, signed in as a visitor at North Park Elementary School on Monday, April 10th, 2017, proceeding to his wife’s classroom, where he shot her with a 357 revolver concealed on his person. He inadvertently killed one student and wounded another during the shooting, before turning the gun on himself.
California laws include a DOJ administered test for firearm owners granting a safety certificate, which expires after 5 years, and a registration process for manufacturers. The firearm registration process ostensibly insures implementation of safety features for each model sold in California, but also adds cost and time-to-market challenges compared to other states or markets.
Gun advocates observe that these “attention” or “revenge” shootings rarely happen where concealed carry is permitted or guards are posted: such shooters prefer unprotected locations. California’s state constitution does not include a “right to bear arms” provision, but many of the state’s laws are being challenged in federal court under the auspices of the 2d Amendment to the US Constitution.
