I mean… if you really cared, its a few hour drive to a state where you can legally buy them. Its not a large burden, and could be done in an afternoon.
Edit: i like the downvotes this comment gets, as if its some sort of morality claim. Its just a fact. Im not personally pro gun, however i dont think the solution is an easy all guns are bad all the time. Its a very complex issue in america.
However, i am very against political theater, California isnt going to to fix gun problems unless they can outlaw handguns, which are used in more than 90% of all gun related crimes. Just like they arnt going to fix water shortages by stopping people watering their lawns or washing cars when around 95% or the water usage is corporations.
