Reports behind terror alert were years old

Ahhh. New revelations about the sources which led to the raise of the threat level. The NYT reports:

Much of the information that led the authorities to raise the terror alert at several large financial institutions in the New York City and Washington areas was three or four years old, intelligence and law enforcement officials said on Monday. They reported that they had not yet found concrete evidence that a terrorist plot or preparatory surveillance operations were still under way.

Again: why am I not surprised?
