Could Martha Stewart go to jail? She sold her ImClone stock one day before the FDA shot down the company's new cancer drug, but no, no, it wasn't insider trading, Martha says, despite her close relationship with ImClone CEO Sam Waksal--who has been arrested for dumping his stock just before the FDA announcement. They share the same stockbroker and, according to phone records, she spoke to him before selling her shares. Not a "good thing," hmm? I can almost picture her in a pair of orange cover-alls at the Womens' House of Detention, making salad bowls out of popsicle sticks and wondering where it all went wrong . . . . Assuming she wiggles out of this one, I still think she should buy (bankrupt) K-mart, and rename it MarthaMart.
