How Did Revelations About Domestic Spying Help Terrorists?

I know I've been harping on this (most recently here), and I'm not going to just keep repeating myself...but just thought I'd point out that Atrios is on this now, issuing a challenge to pro-Bush dead-enders to explain how the NYT revelations about domestic spying harmed our anti-terrorism efforts.

Answer, as I've noted: it didn't, not even a little bit.

It's really, really wrong to misuse national defense arguments in this way--for political ends, that is. But I suppose we should be used to it by now.
