NSA Had Domestic Call Monitoring Before 9/11?

MarkusQ writes "Bloomberg is reporting that, according to documents filed in the breach of privacy suit on behalf of Verizon and BellSouth, the NSA asked AT&T to set up its domestic call monitoring site seven months before the Sept. 11, 2001 attacks. Could it be that they were intending to monitor domestic calls (and internet traffic) all along, and the 'Global War on Terror' was just a convenient excuse when they got caught?" From the article: "...an unnamed former employee of the AT&T unit provided them with evidence that the NSA approached the carrier with the proposed plan. Afran said he has seen the worker's log book and independently confirmed the source's participation in the project. He declined to identify the employee."
