The Wall Street Journal reports (subscription required) that the SEC has subpoenaed 50 hedge-fund advisers as part of its probe into allegations that traders spread negative rumors to drive down the share prices of stocks they were short.

It seems especially zealous given how little the SEC has done to crack down on a multitude of other problems harming investors, like the inadequate disclosures of serious risks that have sent shares of companies like Lehman Brothers (NYSE: LEH) and Washington Mutual (NYSE: WM) tumbling.

Maybe there was some foul play at hedge funds, and maybe it's a good use of SEC resources to go after it. But it's worth noting that, throughout history, every time a bubble has burst, the short sellers who profited from its demise have been scapegoated for their foresight. The men who were at the helm of Bear Stearns (Yes, it was men. Women would never foul anything up that badly!) when it collapsed can blame rumor-spreading short sellers for causing a run on the bank. It's the same excuse that former Enron CEO Jeff Skilling invoked in his testimony before Congress.
