I've open carried several times at SEA since Mainsail was arrested. I've had no problems, even when walking in front of a bunch of TSA. I don't agree that law abiding activity should be curtailed because certain cops can't read or understand the law. That goes double for their superiors.
My main purpose in carrying is protection of self and family. Nobody has a right to curtail that right of mine, regardless of whether it's couched in term of a "rule" or whatever. "Only in a society of cannibals would the right of self defense come into question," is what I told Dave Workman. I believe it so I live it.
