Martha Stewart was convicted for lying to federal investigators and nothing else. Other than that I believe she did nothing wrong. She shouldn't do any jail time and the lesson learned is never cooperate with federal investigators, call your lawyer, take the 5th, and see them in court.
Why do you believe that? You admit she lied. She therefore knowingly lied to her shareholders, which propped up Martha Stewart stock -- clearly securities fraud. Fortunately for her, the charge was dismissed on a technicality (Judge Cedarbaum later ruled that prosecutors could not call expert witnesses to testify that Stewart's actions constituted securities fraud).
"In a 23-page decision, Judge Miriam Cedarbaum dismissed one count of securities fraud against Stewart, which alone could have carried a 10-year sentence."
"Prosecutors had alleged Stewart committed securities fraud when she maintained her innocence in the midst of the investigation in press interviews and at a midyear meeting for Martha Stewart Living Omnimedia (MSLO) before analysts and investors. The government had set out to argue that Stewart's statements were not only false, but that they were intended to prevent the stock price of MSLO from plummeting."
I guess you weren't one of the poor slobs that owned the stock and got screwed by Ms. Stewart. I bet they don't think that, "other than that she did nothing wrong".
