That was confusing to me today as well. Was Atta id'd as being in the country and part of that cell pre 9/11 or not.
Conflicting reporting on this matter. One of the witnesses today said he wanted to correct something that was incorrect in the media. (I felt like telling him none of us would live that long. LOL)
Anyway, he said that Atta was not ID'd as being part of a cell in the US pre 9/11. That's contrary to what I've heard Weldon himself say (I think) and he's as close to this as anyone.
My recollection of the testimony is that Atta was identified as connected to the Brooklyn cell by Able Danger. However, one witness took pains to clarify that Able Danger had not identified Atta as being in the U.S. before 2000. Gotta check the transcript.
