This Bill Moyers interview with Jon Stewart is very illuminating, on a lot of levels.

For one, he truly continues a level of self-depracation of what he does, that I find admirable.
Two, his general analysis, say, of the Gonzales administration, is very right on. 
Three, regarding Virginia Tech - near the end of this interview with Bill Moyers, there is a segment showing Stewart interviewing Allawi, and commenting on the fact that, in Iraq, there is a Virginia Tech massacre, "every day".  In that, this is similar to my thoughts on the subject.

Worth watching.
