Ars Technica article: Why computer-automated mass surveillance is a bad idea

"As the TSA, with its strip-searching of people's elderly grandparents, abundantly proves every holiday season, blunt instruments and scorched earth tactics are of dubious value in catching genuine bad actors.

This is true for face recognition, it's true for biometrics, it's true for RFID, and it's true for every other high-volume automated technique for catching bad guys."
