You're probably right.

The problem, as I see it, is that the false positives are pretty damn costly, both in dollar terms (costing individuals $$$, cost of diverting planes when they find "someone" is on the list, etc.) and civil liberty terms.

I'm not surprised that DHS isn't too worried about the costs, though. That would be out of character.
