Obama pretending to solve financial crisis?

A full criminal investigation into the role the big banks of Wall Street played in the economic collapse has been a promise made by US President Barack Obama that has yet to be fulfilled. In his State of the Union address earlier this year, Obama announced the creation of a mortgage fraud task force - a group that would hold accountable those responsible for the crisis. William Black, associate economics professor for the University of Missouri - Kansas, school of law, explains how aggressive this investigation has actually been.
