It's been a while since I've paid much attention to those investigators who claim—some with credibility, others with a loopy gleam in their eyes—that a conspiracy larger than Timothy McVeigh was behind the Oklahoma City bombing of 1995. I'm thus not sure whether this new report adds anything significant to the story, but it's certainly interesting.
(Don't be misled by the article's headline, by the way. There's not much here that suggests the feds knew this specific plot was coming. There's a bit more, though, that suggests there was more behind the attack than a pissed-off vet with a couple of pals from Michigan.)
