Is there a compelling public interest? What percentage of shootings in California in the past, I dunno, decade have involved someone with a CCW shooting a neighbor over a complaint being filed against them? Is it nonzero?
If the number of shootings where a CCW holder has shot a neighbor over a complaint is substantially smaller than the number of cases where a CCW holder has not shot a neighbor over a complaint, doesn't this just serve to make holding a CCW intimidating in a way that most CCW holders neither want nor need? Most directly relevant to your public interest argument, is the rate of people shooting neighbors over a complaint substantially higher among CCW-permit holders than non-CCW-permit holders?
