Effective Counterterrorism and the Limited Role of Predictive Data Mining, by Jeff Jonas [engineer and chief scientist with IBM’s Entity Analytic Solutions Group] and Jim Harper [director of information policy studies at the Cato Institute]. “Though data mining has many valuable uses, it is not well suited to the terrorist discovery problem. It would be unfortunate if data mining for terrorism discovery had currency within national security, law enforcement, and technology circles because pursuing this use of data mining would waste taxpayer dollars, needlessly infringe on privacy and civil liberties, and misdirect the valuable time and energy of the men and women in the national security community.”
