SAC honcho arrested for alleged insider trading. I’ve yet to see the harm in trading on inside information but I’ll concede that it’s illegal and thus shouldn’t be engaged in. But I notice that no one involved in the mortgage/real estate collapse has even been indicted, let alone tried and imprisoned, and it makes me wonder whether the Justice Department isn’t initiating these high profile insider trading cases solely to create the impression that they’re cracking down on Wall Street when in fact they’re doing nothing of the sort. Where’s Jon Corzine lately? Dickie Fuld? Angelo Mozillo? Ben Bernanke? Chris Dodd? Barney Frank? All safe, all free. I’m not impressed.
