You are all demonstrating you don't know how FR works, nor the article author. FR is a technology that helps to identify, it is not "the authority" and was never intended as such - but hard explaining that to any journalist, or people predisposed by fear journalism. When an FR system scans people and produces "false positives" - that is what you want. The system is tuned sensitive to generate false positives on purpose, so a human can then make the final determination. The point being, a human cannot look at thousands of faces and remain objective, but they can look at a dozen and tell if they have the person they are seeking. The FR system does the labor of throwing away the obvious non-matches, and shows the operator possible matches for final confirmation. That is their design. FR systems are not tuned the other way, because you are trying to help find someone, not be the authority on finding them. Such a system will never know their "false negatives" when dealing with the public - but comparing their ROC Curves ("false negatives", "false positives", "true negatives" and "true positives") is exactly how they are measured and compared when selecting which FR system is better. The key take away is: they are not intended to be an autonomous agent, they are used by a human to help scan more people than they can alone, and it is the human who makes the final identification.
