Not to dwell on Cynthia McKinney, but I see that Charles Kuffner has moved his position slightly, and has convinced me to move my own. I guess there is a purpose to public discourse after all.
My version is that if C. McKinney wants to call for an investigation of 9/11 she should. If she wants to call for an investigation of the connections between military contractors and "Bush Pioneers" she should. But, to mention them in the same breath automatically implies a connection unhelpful to either cause. There may be a connection of course, but... that's a different issue.
