And speaking of making conclusions of responsibility in Madrid...
DailyKos finds something revealing; namely, the conclusion drawing from our administration:

You can tell that Colin Powell served in the military, where one of the most common sayings is "hurry up and wait."
This is what Powell said this morning on Fox News Sunday, three days after the bombings in Madrid:

POWELL: Essentially what the Spanish know, and that is that they can't yet place responsibility. ETA is still a candidate for responsibility, but now with these new developments of the arrests of the Moroccans and the Indians and the tape, I know that the Spanish authorities have to consider that it might have been another group, perhaps Al Qaida. But we really don't know yet.
WALLACE: So just because you've got these arrests, including Moroccans, and you've got this tape claiming Al Qaida, you don't believe it necessarily?

POWELL: Well, it's not matter of believing anything; it's just premature to make a judgment. I don't think we know enough, and the Spanish are very good at these kinds of investigations. And I'm sure they'll get to the bottom of it.

[emphasis mine]
And here's Powell's statement on Thursday, just hours after the blasts:

Secretary of State Colin Powell said he spoke with his Spanish counterpart and offered sympathy and solidarity in the war on terrorism.
"The United States stands resolutely with Spain in the fight against terrorism in all its forms and against the particular threat that Spain faces from the evil of ETA terrorism,'' Powell said.

So, just in case you're confused, here's how it works:

When a quick conclusion in support of a position that would benefit them or their political allies, even if it obscures the truth or inhibits the open inquiry of the truth, the Bush administration favors quick conclusions.

When the weight of evidence quickly tips in favor of a conclusion with negative implications for them or their political allies, the Bush administration opposes quick conclusions, even if delays might inhibit or obscure the pursuit of justice. This seems to be especially true when the weight of evidence tips against the electoral interests of the ruling right-wing party of Spain, which may have lost today's election despite the dubious efforts of Colin Powell.
