The five months in federal prison she was sentenced to she will never serve. Neither will she be grounded for five months, which she would be only subsequent to the prison time. She will pay the $30,000 fine, but that's got to be chump change in comparison with her attorney fees.
Martha Stewart Living Omnimedia Inc. will likely wither and die a lingering death. Prestige is her stock in trade, and her image has been irreparably corroded. She was arrogant. She is a well-heeled thief and got caught at it. Who wants to identify with that?
The sensible thing for her would be to serve the time, and save the money the appeals will cost. Her appealing may salvage some of her prestige, though, and maybe enough to be able to quietly liquidate the company piecemeal. So, in the end, maybe she will end up in the black. Let the punishment fit the crime.
Ken Lay, on the other hand, will almost certainly serve time in prison, probably several years, and have to pay huge sums in both fines amd attorneys' fees. He will be a poor white man then, and have to forever be looking over his shoulder, wondering if someone might be following him with a gun. As a convicted felon, his employment options will be limited. Let's see, what did those Watergate guys do? Wrote books, became ministers, hosted radio, actor. . .
