Its not an equal analogy but that trend back then did land some open carry coffee drinkers with charges so its not unreasonable to think they were a threat.Isn't it though? He had the gun in his hand, but in no other way was acting as if something was going down. Just carrying it (into the store where he got it from). Stupid way to carry a gun sure (even a fake one), but not in and of itself enough to establish criminal intent.
