I once read an article about surveillance with a title along the lines of "A Tale of Two Cities." In it, the author explains that there are two types of surveillance cities that will emerge in the future: one where every park bench is rigged with a mic, every street corner has a camera aimed at it, and where all the data collected is funneled to law enforcement agencies; if you were mugged on some street corner, they'd be able to react to the crime swiftly and with high accuracy. The other city is exactly the same, but all the data is made available to all citizens through an open API; so if you wanted to meet with someone on some street corner, you could decide for yourself if it was safe enough to visit, likely preventing the crime from happening at all. Does anyone know what article I'm talking about?
