Singular. The FBI looked into Maj. Nidal Malik Hasan correspondence with a radical Islamic cleric. Good. They should have. It was certainly alarming on its face.
Many Republicans, including Joe Lieberman, already have a diagnosis for why the FBI didn't make waves about it, and they don't even know what the FBI found:
[Fran Townsend] expressed concern that “political correctness,” and fear of intruding on Major Hasan’s free speech rights, may have interfered with the sharing of information earlier this year, when an F.B.I.-led counterterrorism team examined his e-mail exchanges with Anwar al-Awlaki, a well-known radical cleric, but found nothing amiss.By political correctness, Bushists like Townsend mean observance of legal and Constitutional rights. Free speech? Who needs it!
I know they object to having to abide by the law of the land, but that email correspondence is the single dot they have to connect to a conspiracy that coddles soldiering while Muslim. It doesn't seem like a web of failure.
The Walter Reed fitrep (or unfitrep!) might look like another dot, but it's a garden variety personnel matter. In addition to being undeniably Muslim, Hasan was a really bad psychiatrist, and there's no denying that that is another possible motive for his crimes.
