i'd say, i'd feel unsafe there even if such a story didn't happen to me... or, while there are houses of thin wood, maybe you are allowed to wear/keep a gun?
Wearing is, as well, but it's waiting on another SCOTUS decision for affirmation.
As for carrying in SF, only people named Feinstein are permitted to do that.
There are a handful of cases which ought to end the question on carry in the next year, as well. Either Williams or Masciandaro may do so this year providing SCOTUS grants cert.
