Judging from this news report at CNN, it appears that the judge in Martha Stewart's trial is not going to allow her to present a defense.
"Among the limitations: Stewart's lawyers can't say she was being prosecuted for proclaiming her innocence in the case or for asserting her First Amendment right to free speech. The defense also is barred from saying that the securities fraud charge Stewart faces is a novel application of securities laws, and from making statements that would tend to show the government's motives in investigating or prosecuting Stewart were improper. The defense also can't say that the fact Stewart and former broker Peter Bacanovic aren't facing criminal insider trading charges means the government doesn't believe they committed such a crime."
Why bother with a trial. Just throw her in the bog and if she floats then she's a witch.
