Like I Said
Nukes & Spooks writes that a New report questions data-mining as counter-terror tool.
I have been complaining for years about this approach for gathering intelligence, my first mention on this site was in December of 2005, but earlier than that in comments other places and using exactly the same analogy that the National Research Council uses in this report: a needle in a haystack.
They keep dumping “hay” on the stack [sucking up data] which makes it more unlikely you’ll ever find the “needle” [usable intelligence]. We need less data and more people looking. Data-mining uses up resources that could be used more effectively to actually increase our ability to find what we need.
