Why doesn’t mass surveillance work? That is the problem with false positives and false negatives. If you go look, our program is 99.9 percent effective, and that sounds really good, but when you think about that in the context of a program, that means one out of every thousand people is going to be inaccurately identified as a terrorist, or one out of every thousand terrorists is actually going to be let go by the system, and considered to not be a terrorist.
And the real problem is that our algorithms are not 99.9 percent effective. They are about 80 percent effective at best.
