Let's see what Kean and Hamilton really said, shall we?
Now, I'll grant you this, it's quite hard to track down that quote. There are so many truther sites repeating the "set up to fail" quotemine without including the full context that I had to look down to page 8 on Google to find it. That's how the truth movement suppresses information, by burying it under a torrent of misinformation. But when we actually dig down to the reality, it turns out the truthers were misleading us, every time. Kean and Hamilton actually view the work of the 9/11 Commission as a success despite the Bush administration's attempts to block its work. And this, let's remember, is what truthers brand as the government's official theory - one that the government of the day actually tried to hide, because they were afraid of looking incompetent.
