Kurt Vonnegut's "Harrison Bergeron"

After reading the short story "Harrison Bergeron", I am confused more than anything.  I understand the story, but I don't really understand what happened to Harrison and the ballerina.  I assume they were the emperor and the empress that were shot, but why did George and Hazel become upset about what they viewed on the television and then all the sudden forget it?  To me, it seems like this story is trying to get the point across that in the future, the government will be in pure control of everything and everyone.  This is a scary thought to think about.  It is scary to think that the government will disfigure people and their abilities so that everyone is equal.  This was a strange story, and was too short!  I wanted to keep reading.  I wish there had been more to the story.  It just seemed like the plot was given, Harrison escaped jail and was shot, then the end of the story.
