Marc Thiessen Caught Selecting Facts To Support His Argument

Marc Thiessen, speechwriter for former President George W. Bush and Secretary of Defense Donald Rumsfeld, appeared on Comedy Central's The Daily Show on March 9th to promote his new book Courting Disaster. His interview at times was very contentious, but what satisfied me the most was a portion of the interview nine minutes in, where Thiessen states that America was not attacked for seven years after September 11th's terrorist attacks. John Stewart countered, stating that we were not attacked for seven years on American soil after the first World Trade Center bombing. Apparently John hit a sore spot because Thiessen felt it was clear to show up his host, citing the the bombing of the World Trade Center, bombings in East Africa, the bombing of the USS Cole, and then finally September 11th as proof that the United States was attacked in the seven year period John Stewart mentioned, but John had some points to make of his own, mentioning the bombings in Britain, Afghanistan, and Iraq (Stewart could have also mentioned the 2004 Madrid bombings as well to illustrate his point). John Stewart then chastised Thiessen saying that Thiessen lives in a "selective world" and then jumped to commercial, much to Thiessen's dismay - the show was over and the interview would continue on the internet, but Thiessen felt that Stewart steamrolled the interview and that he would not be able to get his point out over the air, which I would have to say that Stewart did interrupt Thiessen quite a bit, but unlike the rest of the mainstream media, he did not allow his guest to perpetuate lies and selective reasoning to support his argument. Why are reporters afraid to ask these questions and stick to them?
