Yes, Hamilton and Felzenberg have contradicted each other - one denies Atta was ever mentioned in this context, while the other claims the info was heard but dismissed because supposedly Atta was not yet in the country in late 1999. fwiw, just because "travel records" show him entering the US in the summer of 2000 does not mean he could not have been here previously - especially since terrorists often have multiple identities, false passports, etc.
An earlier report I read this evening (they're all running together) about Snell points out that the German cell members covered for one another when some were out of the country so that their absence wouldn't be tracked.
Snell should have known this when he heard the briefing. Good grief!

Re the 1999 vs 2000 presence of Atta in the US, the discrepancy could be explained by something as mundane as the testifier mixing up "before the millenium" and "before the WTC disaster." Just as we all may be susceptible to writing the wrong year on a check in any January, this particular testifier could have said 1999, when he meant "one year before 9/11."
