Don't believe I've ever seen so many paranoid people in one place.
Well, in CA and related to firearms, the common attitude I have encountered is from suspicion to outright "you're dangerous" when talking to non-LEO's about being a shooter. Statements from people like the LA Mayor, Chief of LAPD and Sherriff Lee Baca re concealed carry and self-defense are not supportive.
The video of CHP officers slamming an older woman to the floor to help Ray Nagin disarm civilians after Katrina is well within the "it can happen here" range in CA. Details omitted, I have met some great LEO's and some scary bums. Since it is unlikely you will know right off which you are dealing with, you need to exercise care.
If you want to call that paranoia, up to you.
