Okay, I hope no one takes exception to my caustic sarcasm but...
Who cares about that crazy city? The only thing good that came out of there was Dirty Harry.
Although if you live there or have a loved one that lives there, it's more than understandable to be concerned.
But San Fran has for a long time harbored a politically esoteric group of citizens, and the handgun ban, enacted by a popular vote, reflects this. Many professed liberals think that an all-out handgun ban is just going too far, but in that city, such a ban was able to easily pass.
If the phenomenon begins to spread and it becomes illegal to own a handgun in Los Angeles, then I'll be worried. But San Francisco being what it is... well, it's just not something I tend to concern myself with. I still have a reasonable degree of faith that the new law is going to be ruled unconstitutional at some point, anyway.
