Too many people expect these guys to show up at their job and be error-free. Human error will always be a part of being a NBA ref.
What action do you propose should be taken to ensure that there is no superstar treatment? Certain players earn certain respect for what they have done over the course of their careers. That's how the NBA has always been. It's not in a memo that the League office passes around every season, it's just the way things are. Larry Bird was given calls that JJ Re doesn't get...and i think that's how it SHOULD be. Tim gets aways with things that Mark Madsen could never get away with, and i think he has earned that.
Referees are human beings with varying emotions, judgement and personal biases. I'm sure they do their best to suppress certain emotions and feelings for the sake of their job, because like most everyone, they want to be perceived as competent in their profession. I'm not exactly sure what "steps" could be taken to "correct" these biases and emotions, because they will always exist.

Punishing referees for ridiculous behavior is something the NBA already does (see Joey Crawford). And i just don't think it's practical to start punishing refs per bad call. Referees don't have the benefit of slow motion...they are making split-second decisions in front of thousands of screaming fans while the best athletes in the world are moving at top speed right in front of them.
Bad calls happen in every game, and to every team. Superstars get calls that scrubs do not get. That's just how the game is, and that's how it's always been.
The best teams win.
