THE WALL STREET JOURNAL on the airliner plot:

Let’s emphasize that again: The plot was foiled because a large number of people were under surveillance concerning their spending, travel and communications. Which leads us to wonder if Scotland Yard would have succeeded if the ACLU or the New York Times had first learned the details of such surveillance programs. . . .

In short, Democrats who claim to want “focus” on the war on terror have wanted it fought without the intelligence, interrogation and detention tools necessary to win it. And if they cite “cooperation” with our allies as some kind of magical answer, they should be reminded that the British and other European legal systems generally permit far more intrusive surveillance and detention policies than the Bush Administration has ever contemplated.

It’s also worth noting, though, that a tip from a worried British Muslim played an important role, which is why measures that over-alienate Muslims and immigrants are likely a bad idea. Striking a balance is hard, especially with all the political posturing going on.
