Do you think she is "innocent"? Or that the jury won't care?
The many cases of cheating that you describe are probably cases that were not prosecuted. Once a person manages to find themselves in front of the jury, different judgements will apply.
Based on what I have read, Martha cheated some buyers of Imclone stock out of money they paid for the stock. It is little different than if Martha had burgled their homes while they were on vacation and stole their life savings.
The fact that her secretary broke down into tears says "I love Martha no matter what" and we both got caught with our fingers on the computer keys.
