By his own admission, Wired Magazine Senior Editor Kevin Poulsen is withholding a large majority of chat logs that could prove WikiLeaks founder Julian Assange did or did not conspire with the US soldier accused of leaking a cache of diplomatic cables.

In his Monday column, Salon's Glenn Greenwald called Poulsen's actions "one of the worst journalistic disgraces of the year."

In June, Poulsen published what he said was about 25 percent of the conversations between Pfc. Bradley Manning and ex-hacker Adrian Lamo.
