They do have a right to tell you what to do, as long as it's not incriminating, or beyond a fair and reasonable request. I don't think the cops were asking him too much, nor do I think it was really arrestable. The part that makes me pause to think is that the executive who was arrested did indeed egg the fans on by "tweeting" them that Justin was there signing autographs, when he clearly wasn't, which probably made the situation a hell of a lot worse.
But who knows how this'll go, hopefully it's thrown out, but you never know.
