MR. GIBBS:Well, David, I don't think the president has shifted his position. I think what the president said on the Thursday in which the memos were released, all the way through this, he's been consistent and clear: those that followed the legal advice, the four corners of the legal advice in good faith, those people should not and will not be prosecuted. But the president, as you know, David, doesn't determine who knowingly breaks the law or not. That's set up and devised by the Justice Department and other lawyers and legal entities to decide those questions. The president does strongly believe that these memos are a time for reflection on where we've been and not for retribution, and that we must look forward. I think the most important thing to understand in all of this debate, David, is the most important step that was taken in the first almost 100 days of this administration relating to this debate was for the president to ban, once and for all, the use of enhanced interrogationtechniques by anybody involved in this government.
