Greenwald discusses the possibility of writing a book:
I could have just sat back and not triggered any more risk for myself, or any more sort of recriminations. But, you know, the premise of what I was doing all along was that I wanted to report this story differently than the normal, unwritten rules between journalists and the U.S. government that typically govern how these things function. I wanted to be as aggressive as possible in how I reported them; I wanted them to actually make an impact.
