I doubt it. People wanted to see Martha Stewart taking down several pegs, that's the chief reason she was convicted. Most people believe she was charged and convicted for insider trading, when the fact is that she wasn't charged with that at all.
If I was a liberal conspiratist, I'd say that Lay's trail and possible conviction at this point are politically motivated. There was plenty of time to try him before, but with the election looming close, the Republican's can say they're doing something about the scanal and point to the either ongoing or just ended Lay trial as proof.
