I have a feeling the Feds have been on this case since at least Thursday. Yesterday, Moose said he was sending members of "other agencies" to the schools, but that he didn't want to reveal what those "agencies" were. This morning he said there were "special agents" working in the "building behind him" that didn't care about their "ego." Translation: this is Dem territory, and they've been told to take a back seat, and/or the Feds themselves uncharacteristically decided to take a back seat from the beginning.
Carl Cameron of Fox asked Ashcroft today if this is terrorism. His answer: "I'm not in a position to answer that." Last night, Cameron said "officials" in the DOJ were concerned that terrorism had been ruled out too soon.
In response to the histrionics of the PG County Chief waving a letter to Justice asking for help on the basis of this being a serial killing, Ashcroft was quoted as saying something to the effect that the serial killing angle is why they have been providing assistance (past tense).
