HOW THE COPS WATCH YOUR TWEETS IN REAL-TIME Recent leaks about the NSA's Internet spy programs have sparked renewed interest in government surveillance, though the leaks touch largely on a single form of such surveillance^^the covert one. But so-called "open source intelligence" (OSINT) is also big business: and not just at the national/international level. New tools now mine everything from "the deep Web" to Facebook posts to tweets so that cops and corporations can see what locals are saying. Due to the sheer scale of social media posts, many tools don't even aim at providing a complete picture. Others do. For instance, consider BlueJay, the "Law Enforcement Twitter Crime Scanner," which provides real-time, geo-fenced access to every single public tweet so that local police can keep tabs on #gunfire, #meth, and #protest (yes, those are real examples) in their communities. BlueJay is the product of BrightPlanet, whose tagline is "Deep Web Intelligence" and whose board is populated with people like Admiral John Poindexter of Total Information Awareness infamy. BlueJay allows users to enter a set of Twitter accounts, keywords, and locations to scan for within 25-mile geofences (BlueJay users can create up to five such fences), then it returns all matching tweets in real-time. If the tweets come with GPS locations, they are plotted on a map. The product can also export databases of up to 100,000 matching tweets at a time.
