I hope the OP gets some answers. I do think it is a little odd that the officer was so concerned, that he called for back up and not one actual sheriff's car appeared. I think most of us have seen sheriff cars all over WDW roads. If someone was going to be arrested, it certainly wouldn't be via a golf cart. Golf carts indicate security guard to me. I would have called the sheriff's department as soon as I got back to my hotel.
