This sentence is from a very good post by Stewart Baker at Volokh Conspiracy discussing the recently declassified FISA court materials. Don't know whether he's right, but two points he makes:
- the "wall" between law enforcement and intelligence which played a disputed role in the failures to prevent 9/11 was unreasonably enforced by Judge Royce Lamberth.
- cultural differences between IT types and legal types may have played a big part in the problems. (That's an attractive argument to me: I believe in Murphy's Law.)
