Corporate governance morals

The treasury secretary, Henry Merritt Paulson declared that there will be no bailouts this weekend for Lehman as bailouts result in the weakening of the compliance of companies with the corporate governance framework. But I often think why such discrimination with Lehman? Why no bailouts for Lehman when there were bailouts for the rest of the falling institutions even a week before Lehman's fall?

It wasn't the bailouts that were making the compliance weak; instead it was the weak framework which did not make the compliance so stringent. It was not just about the poor corporate governance of Lehman. If it would have been so, then why all the financial institutions of USA were failing?
