> First, the possibility that the logs contain more evidence of Manning's or Assange's guilt
You seem to think its ok for Poulsen to hide the logs if doing so would make Manning look better, or if it would somehow make for a fairer trial. But Greenwald isn't arguing that Poulsen is just making Manning look bad.
Greenwald's Wired critique is based on the idea that journalism is about discovering truth. Poulsen is hiding that truth, whatever it is -- that's what makes it inexcusable.
