The media--and the Obama Administration--know that if the bombings are tied to radical Islam (and the only way you can say they weren't is to ignore the mounting evidence), that will open up a broader discussion in this country about the increasing threat here from those who have been radicalized--how it's happening, who is doing it, and who is financing it. That's actually a discussion that needs to happen, yet the media and the administration seem determined not to let it.
