Ed Bott of ZDNet has compared the original Washington Post piece on PRISM with a newer version, highlighting the key areas changed. And as @GabrielMalor points out on Twitter, “Did you notice that WaPo made major stealth-edits to its PRISM story that completely undercut it?”

Do read Ed’s entire analysis. I wonder what else is going to change over the coming days? Maybe we’re looking at Dan Rather 2.0, with a fake-but-real PowerPoint presentation?
