Whenever a crime is committed and there is a mystery as to whom the actual perpetrators of the crime are, it's always a good starting point to take a close look at who made the most money from it.
"According to regulatory filings, RawStory.com has found that Goldman Sachs sold 4,680,822 shares of BP in the first quarter of 2010. Goldman's sales were the largest of any firm during that time. Goldman would have pocketed slightly more than $266 million if their holdings were sold at the average price of BP's stock during the quarter.
If Goldman had sold these shares today, their investment would have lost 36 percent its value, or $96 million. The share sales represented 44 percent of Goldman's holdings -- meaning that Goldman's remaining holdings have still lost tens of millions in value."
