OK GUYS, THE PROBLEM IS SOLVED!!! No fuss, no bother, no shouting, no threats. Here's what happened today.
I locked my weapon in the car and went thru security and did my business on the 3rd floor. On my way out of the building I stopped in at the last office before the exit, the County Admin. Office. The receptionist called the Division Manager, George Reid, who came out from his office. He has overall responsibility for security in the building, so he is THE MAN to talk to about all issues about guns. He is a very amiable guy, which madethe mattermuch easier to discuss. He brought with him a copy of a 2005-dated court order restricting all areas of the 2nd, 3rd, 4th and 5th floors from firearms. With a complete copy of the RCW on the counter in front of us, I explained the difference between Section -.050, conceal carry, and Section -270, open carry. When I was finally able to get the words out about carrying OUTside the security perimeter and that no license is required for OC (under -.270) he finally agreed that they only need to ask for a CPL for CC and NOT for OC. The conversation ended with him saying "I'll take care of that for you".
I said I would confirm the discussion with a letter.
