The first thing a visitor sees when arriving at the title page to the Brookings Essay, "The Big Snoop," are six chilling words: "Some data we see about you." Beneath that, the site lists your ip address, hostname, city, region, postal code, the browser you're using, your time on the page, scroll depth, and what operating system you're running on what kind of computer. That's a good introduction to this six part essay by Brookings Fellow Stuart S. Taylor, Jr., which elucidates the views of four very different experts of varying political backgrounds on the topic of national security vs. individual privacy. For those of us who enjoy in-depth analysis of complex, hot-button topics, this interactive page should not be missed.
