Who wouldn’t want to know everything? If we could make sure we knew absolutely everything, nothing unfair would ever happen to us again. We would know, for example, whether the federal government’s secret reason why it’s authorized to collect the phone records of every Verizon customer is an airtight legal argument or a drawing of Mayor McCheese having his way with the Hamburglar. If we knew who all the terrorists were and whom they called, and who all those people called, we would have a sort of terrorist social network. I call it Friendsterrorist. It’s a list of everyone who is bad, and once we have it we need only shut those people down and live forever, like Myspace. Today is Friday, and what you don’t know could fill a book you aren’t allowed to read. Won’t you speculate on the contents with me?
