Can a deputy ask the names of people you know in an area and can he fol low you after the stop?

He was doing his job, get over it. By rudely you mean he was calling you names, threatening you, or yelling at you? Or did he just, authoritatively, ask you what is your business was driving down this road (that he has probably driven down a hundred times and he knows your car does not belong there). There is a difference. Wouldn't you want him to do that if it was the deserted country road your family lived on?? I know that is what I would want him to do. For all he knows you could be a murderer, thief, or a rapist. Stop being so sensitive, apparently he was not out to get you otherwise you would be in jail now.
