Reason had this story of a BNSF employee who was stopped by a cop in Arkansas as he was doing his job (although in a rental vehicle - not flagged with Company logos) and it pretty quickly got out of hand.
Clearly the cop was over-reacting (seemed to be alone which is risky) and although I think he was in the wrong - and truly could not have been more cooperative - I can see how his quick reply's/actions may have been un-nerving to the cop - especially where we know they are being trained to treat VIRTUALLY ANY action as hostile. This is reinforced by the I would say by the very unsympathetic media portrayal there are facing which just makes them ornery.
Here is body-cam footage of the encounter.
And here is the visit to the Chief of Police to discuss his complaint.
