From "in re Brickley 70 P 609":
70 P. 609, wherein the Idaho Supreme Court found unconstitutional a local ordinance that prohibited the carrying of weapons within the city limits. The court there held such an ordinance to be a violation of the State constitution's right-to-arms clause which was substantially the same as the Illinois provision. The court in Brickley went on to say, "The legislature may, as expressly provided in our state constitution, regulate the exercise of this right, but may not prohibit it. A statute prohibiting the carrying of concealed deadly weapons would be a proper exercise of the police power of the state." (Brickley, at 599.)
Idaho has staewide unlicensed OC, So has WA and OR...all from similar rulings. Because of our state constitutions (which are very similar to OK's state constitution) regulation of OC is extremely limited, like to court house, jail, MH hospitals. OR just had the Oregon University system gun regulations overturned, and I wish we would do the same here in WA. The university has overstepped it's bounds and needs to be corrected. There is a case going on right now in ID over the same thing,
