The lack of laws around weapon storage are wild. As a part of gun culture I can tell you in the US the gun culture around you is going to determine how safe the area is from guns, and in no small part due to storage habbits that somehow come down to the culture rather than the law. When I see divisions between red and blue state gun crime, it makes intament sense to me having seen how gun culture is in each place. Even the conservatives in liberal areas are generally more careful with weapons than the conservatives in area where they are the majority. Advertising is another problem that imo is a massive contribution to the negative aspects of US gun culture. Not many outside of the culture would see this but if you go to a web site that sells gun accessories and buy something, just wait for the bonkers catalogue they send you in the mail later. For me it looked like a mall ninjas paradise, with just enough inflammatory marketing to not be punished for it, and if we can't reign that in as well I fear all we will be doing is chnging what type of gun the next shooting will be done with.
