My aunt and uncle live in a not-so-great neighborhood near LA (in the best house on their block, stupidly), and their reaction to getting their yard broken into was to security-feed their house up the wazoo. You can't even open a window there without the alarm going off.
No guns, as far as I know. Too afraid of having it be used against them.
They're likely call-911 trigger-happy though.
But yeah, if you're trigger-happy without ACTUALLY having good reason to be (like being in an unsafe neighborhood, not just having a house and material possessions), it just makes you look insane. No wonder why people in LA and westward don't like people from the OC.
