Apparently, you are unaware of the fact that states have open borders and interstate highways, which negate local gun control laws and only enforces the fact that we need better national gun control laws. Too many guns end up in the hands of toddlers. A comparison of OECD countries mass shooting statistics for over the past 30 shows America had 78 mass shootings whereas Germany was second with 7.
Your own claims about gun crime negate your claims about the Mulford Act for which you present absolutely no evidence to support your rather hysterical claim.
Affordable housing is the best you could come up with? Every city in every state has that problem. More dogma.
