Question: I'm trying to write a letter to the editor of my local paper about their report of a man who doesn't think the rules apply to him. Is there a word for this? He's a bit of an egoist, demanding to speak at city council meetings after the public hearing portion of the meeting has been closed.

Answer: 
You can use *egocentric*, or *egocentristic*.
What about just *selfish*? He certainly seems so.
