Just to repeat myself for the benefit of many, many people who are emailing me: I am NOT denying that Martha Stewart should be in jail. I am NOT saying that selling a stock about which you happen to have information that the buyer does not is exactly the same thing as insider trading. (I am saying that it is hard to distinguish from a hypothetical analogy a reader brought up.) And from now on I am going to take Jonah’s advice and lay off this subject. I hope my correspondents follow suit.
