I think we as a society know these guys are terrorists (those who arent in complete denial), but don't want to admit it because they are typically white, born on home soil, and could be someone we know. and that becomes a who can we trust? scenario.
We are just starting to ask ourselves if our government uses tactics which provoke terrorrism, and if so, do they care?
i agree, on some level it seems intentional-- they obviously aren't decrying it or calling war against it like they did immediately after 9/11. guess we've nearly tapped all the oil here.
