I live in a 'shall issue' county in CA and knew I could get one, but just never got around to it till about three years ago.
I am a Realtor. An older Realtor in town (older guy) was brutally attacked during an open house in a decent neighborhood on a pretty Sunday afternoon. Was beat in the head with a crowbar and left for dead. They got $17. He was able to drag himself out to the sidewalk and get somebody's attention. He was in hospital for weeks and almost died.
That did it. Wife and I both got one. We are both always armed now. Can be a pain sometimes, but since I don't have a crystal ball, I always have it.
From what I've read since, there are probably more CCW Realtors than any other non LEO occupation.
