As is usually the case, this latest shooting took place in a state with restrictive gun laws. In fact, California's gun laws may be the nation's most onerous. California not only registers all firearm purchases, but California residents must obtain permission from their local police before they can legally concealed carry guns. Among the things a Californian must do to obtain permission to legally concealed carry a gun is show "good cause" why the government should allow him to concealed carry.
California's Mulford Act prohibits lawful gun owners from openly carrying legal firearms. This law was passed in the late 1960s and signed into law by then-Governor Ronald Reagan. The impetus for the law was the Black Panthers' armed patrols aimed at protecting the residents of African-American neighborhoods from police brutality.
The Mulford Act is hardly the only example of a gun control law motivated at least in part by racial animus. As Tiffany Ware of the Brown Girls Project, an initiative that teaches African-American women responsible firearms ownership and usage, says, "Throughout much of American history gun control was a method for keeping blacks and Hispanics, 'in their place.'" One of the earliest examples of gun control was laws prohibiting slaves from owning guns. After slavery was ended, Jim Crow laws denied African-Americans respect for their Second Amendment rights.
While the modern gun control movement is not explicitly racist, it is still likely that new gun control laws will disproportionately harm African-Americans and other minorities. Concerns about this are increased by cases like that of 32-year-old Philando Castile. A police officer who had stopped Castile's car shot Castile after Castile told the officer he had a firearm in his car.
