Martha Stewart got a year in jail, essentially for obstructing injustice-- lying to the FBI about something that wasn't a crime, but where her lie messed them up. Jail isn't any fun, even for a short time. If they have more than a "little white lie," prosecutors have a lot of discretion to push for things that can make peoples' lives miserable for a long time. Like mjs001 says, they probably have much more.
