Sometimes, a government agency will post a PDF that doesn’t contain searchable text. Most often, it’s a scan of a printout. Why? Don’t the NSA, the Department of Justice, etc., know how to convert Word (or whatever) directly to PDF? It turns out that they know more than some of their critics do. The reason? With a piece of paper, you know much more about what you’re actually disclosing.
