Perhaps with the current economic situation in America, Obama does not wish to place the country at risk for law suits due to actions of people one might construe were working for the U.S. government. My own feeling is that the people of this country should not be held responsible for the actions of the Bush-Cheney administration. While their actions were supported by some citizens, they were not acting in behalf of the country but on their own in pursuit of power or perhaps in the interest of major oil in grabbing control of Iraq oil fields.
