i guess i would agree with dr. ekman in the sense that we are at the point where there's two things going on. most of the studies, if you look at something like voice stress analysis and look at the -- there was an analysis done coming out of the defense department, what you basically show in most of these studies is no more than chance, and agreeing with both of dr. hartwig and ekman, there's a lot of controversial here and very little science and validation. it's not just about field evaluation when you can do it. again, there has been a committee established on the spot regarding the report. i'm on that committee. and we have not been asked to do any scientific validation of the overall program, just to look at one pick thing is, are the results different than chance? i'm agreeing here is what's really needed on these issues before we continue to invest more money is to really establish without, you know, putting any information at risk and stuff like that, establish a baseline about what's doable, what's not doable,
