I realize that what you are all doing is an experiment to exercise your second amendment rights. However, there are many LE profesionals that may see you with a firearm and consider you a danger to themselves and a threat to unarmed citizens. With that in mind they will probably draw their weapons and put you on the ground.
You will then retain an attorney and even if you are in the right it will cost you thousands of dollars to prove it. I believe there are 57 district attorneys in the state of Kallifonia and all will interprite the law differently. This mimmics the off list lower crowd of which I am one. The other problem is the reasoning for actually carrying a firearm on a daily basis which is self defense. An unloaded weapon is as useless in a gunfight as a pearl neckless. Yes I carried for 10 years without authorization but it was necessary. I was a licensed blaster and carried up to 2000 lbs of explosives to blast sights from my magazines but was unable to secure a gun permit. I got my yearly explosives permit from Fresno County Sheriff internal affairs dept., the same dept. that would issue a gun permit. When Sheriff Pierce took over they actually called me to ask if I still wanted a CCW. If you carry concealed and do it right no one would know any more than if you were carrying a wallet. Carrying open invites a well organized criminal to disarm you as well as beat you with your own weapon after he slips it out of your holster.
The reason for carry is to defend your life. In order to do this you should be formally trained ( Gunsite, Thunder ranch, DF Training, etc) and then practice constantly.
Most gunfights are over in a couple of seconds. I do not mean to insult any of you but I go through three day training courses every couple of months and this is what I am taught. If we are not able to engage a target at the sound of the timer from hands at our sides at 5 yards in 1.2 seconds we get drilled until we can. We are drilled in all 3 types of malmunctions and timed for these as well. I am very serious about the responsibility of carrying a firearm.
