The first one pleads for us to believe that the memos we will mention should not be taken too seriously.
Yeah right. This notion was indicated in a "C.Y.A." memo 5 days before Bush II left town.
The Second one contrasts what was said in private and what was said in public by Bush II propagandists.
Newsweek journalist Mike Isikoff explains the Third memo quite well, so we will simply make some quotes from his article and suggest that you go read it.
This Third memo says:
"First Amendment speech and press rights may also be subordinated to the overriding need to wage war successfully," Yoo wrote in the memo entitled "Authority for Use of Military Force to Combat Terrorist Activity Within the United States."(Newsweek, emphasis added). In other words Bush II was informed by his Department of Just Us that he could shut down the press and free speech so he could whip some "turrisstss ass".
