Similar story is Paula Deen being fired by everybody, her next cookbook canceled. I'm less exercised about story since people are fired for all manner of silly reasons that might reflect poorly on a company, plus its not a government prosecution.
In this case, she was ostensibly fired for her admission that she used the n-word some number of years ago in describing someone (black) who robbed her. It came out in the course of an ongoing harassment lawsuit against her by an employee. I don't think using a racial slur years ago should count for that much. I don't think using it yesterday should necessarily count for that much if the person is sufficiently apologetic.
