You're not going to see this in California, you are wildly out of touch.
This timeline hasn't exactly proven stellar so far.
You're right though - California did a good job restricting guns. Until that gets overturned (which at this point, I think it will). On the other hand the reason California is so for gun control was originally to prevent the Black Panthers from marching with guns (seriously - gun control in California is deeply racist in origin).
Given all this I just think we'll get there and we'll get there faster than we expected, and we'll all have to pretend to be shocked and then it will become normal.
