Dont think we should burden the police beyond reason. It may be too time consuming to check out a persons right to open-carry. So you are there, and he is there, when both of you ought to be about your business. in this instance, it ought to have been the manager who was doing all this stuff while waiting for the police.
In Arizona if you want to open carry, you need a weapon. If you want to carry concealed, in your pocket, you need a weapon and a pocket.
Maybe the Po-Po shouldn't be there. No laws were broken and every human has the right to open-carry.
