After years of plugging away as a soldier in the peace movement, Cindy has finally reached the exalted state of Celebrityhood. And if it costs her heroic son's reputation and her marriage- so what?- just keep the tape rolling. After all, your time only comes around once in a lifetime.
This crusade of Sheehan's hasn't cost her son's reputation, hasn't affected it in the least, and can't affect it. He died for his country, doing the work deemed necessary for our defense by our president and his advisors. Her son died bravely for a good cause. NOTHING she can do will ever change that.
