It will only take one law suit and that will change. I would hope that Snoco deputies would know the law if they were going to put in a possession to be sued.
If I worked for Community Transit I would inform them that this policy will get them a civil rights law suit (section 1983) as OC of an unloaded handgun is legal without a CPL, and loaded OC of a handgun is legal with a CPL.
I don't give a damn what Community transit's Policy is, I do care what state law says.
Ask them if they have ever heard of Rosa Parks?
