Two Bears says-

"I am VERY well aware of false positives. I confronted false positives every day when I worked in the field of Computer Anti-Virus research.

I did not say anything the day the device was found, and the positive field test was reported.

When I wrote the message; another more accurate test HAD been performed, and CONFIRMED the device DID contain Sarin."


As of today, May 19, 2004, 5:51 EST, the results of any more accurate (than the false-positive-prone) field screening of the supposedly sarin-armed IED have not been publicly reported. So, it is still to early to say it has been "confirmed".
