So, you're all in favor of government regulation then, right? Investigations that find something wrong will lead to oversight and regulations, unless Congress has changed its ways. Investigations that find nothing wrong will just waste time for executives trying to run their businesses.
IMO, if the system isn't working the way everyone likes, it's because of the way commodities/futures are bought and sold. Change the mechanics of trading to what everyone agrees on.
I just think this is a witch hunt looking for blame finding and an opportunity to add Congress'
light touch to the the industry.
