US Prosecutions Off - Financial Meltdown

There has been one prosecution which ran for 2 weeks resulting in an acquittal. In the way of the US a juror was interviewed and was supposed to have said that she would like the defendant to handle her investment account. The AIG prosecutions are not going ahead for mysterious reasons and it looks as if no others will. The only explanation which makes any sense (except in terms of legal proprieties) is that the banks and merchant banks offered muted opposition to the reforms which have now been passed by Congress on the basis that the witch hunt was to end. What then is the meaning of having a majority in both Houses? The shine is definitely going off President Obama's administration.
