Jeremiah Cornelius writes: Bruce Schneier, security expert (and rational voice in the wilderness), explains in an editorial on CNN, why "Connecting the Dots" is a "Hindsight Bias". In heeding calls to increase the amount of surveillance data gathered and shared, agencies like the FBI have impaired their ability to discover actual threats, while guaranteeing erosion of personal and civil freedom. "Piling more data onto the mix makes it harder, not easier. The best way to think of it is a needle-in-a-haystack problem; the last thing you want to do is increase the amount of hay you have to search through. The television show 'Person of Interest' is fiction, not fact."
