Last April, we commented on the most blatant (pre) revolving door we had ever seen at the SEC (and there have been many): the departure of the SEC’s head HFT investigator, Gregg Berman, who during his tenure at the agency (whose alleged purpose is to keep the “market” fair, efficient and unmanipulated) did everything in his power to draw attention away from HFTs. He did that, for example, by blaming Waddell and Reed for the May 2010 flash crash.
