I won't argue with that, but why don't you go strap a rifle over your back and take a stroll somewhere very public. My money for the big city cops still says you'll take the ride.
My fear is that if this right isn't exercised, then it will surely go away. Would anyone be interested in doing a group open carry walk or meetup somewhere? As the guy up north did, I think it would be wise to look into local ordinances & notify the local PD ahead of time.
