Democratic Senator Patrick Leahy Proposes Investigation of President Bush's Policies

In another question posed to President Obama, the President was noncommittal on Democratic Senator Patrick Leahy's proposal, who wants an investigation started on President Bush's Administration. In what he calls 'the Bush crime family', he wants a 'truth commission' set up to investigate Bush's policies which would also include promoting the war in Iraq, and incarceration techniques which include torture, besides the known form of torture called 'waterboarding', in which both Bush and former vice-president Chaney admit that took place. Up to this point, this may be the first time that anyone has challenged Bush polices.

Just prior to taking office in January, he did mention that he does not favor prosecuting any of Bush's officials on how they practices their counter-terrorism techniques, but at least he mentioned that "I will take a look at Senator Leahy's proposal... but my general orientation is to say let's get it right moving forward".
So it appears that he is willing to forgive Bush for his failed policies, even after he so strongly criticized Bush for his policies for the last 8 years; even after he is accusing President Bush for putting the economy of this country "in a tailspin".
This sounds like a double standard to me. Personally, I also believe that he should be looking forward also with the  present and future of governing this country in a way that President Bush did not know how to do, and I believe that he is doing a great job in that regard. Maybe he forgets the reasons why he has had so much work lately and that it never seems to stop. Because of the failed policies, President Bush did so many things wrong, and doesn't appear to have to be accountable about his actions. You and I must be accountable for our actions when we are on the job at work. Why doesn't President Bush have to be responsible?!?!?!
