How does harrison rebel against the laws of 2081? Who is Diana Moon Glampers?
It's been a little while since I've read Vonnegut's "Harisson Bergeron," but since no one has helped you out yet I'll try to give you the information you need. Harrison rebels against the system that would force everyone to be equal. He rebels by breaking out of jail, declaring himself emperor, taking off his handicaps, and taking a woman for his own. If I remember correctly this all takes place on live TV, which of course really angers the leaders of any totalitarian-like society.
Diana Moon Glampers is one of these leaders, and she is the one who puts an end to Harisson's rebellion--by shooting him and his girl. I hope this helps.
