I'm not prepared to defend a rogue organization disguising itself as a journalistic effort until they are prepared to answer some of the same ethical questions that CNN and other journalists are faced with every day.
Here's a few good questions for WikiLeaks (they are not mine- they were posed by the Center for Journalism Ethics):
Is there any secret information the site would not publish? If so, what is it and why?
Does the site agree there are valid reasons for secrecy in some cases, and if so, what are those cases?
Would WikiLeaks publish NATO codes for protection against nuclear attack? Would it publish the security plans of energy installations or airports against terrorist attack? Would it publish information that would place in danger individuals, informants, or soldiers?
Could WikiLeaks please tell me more about its editorial processes? Since it likely won’t identify who makes the decisions, can it at least explain in detail how it decides what to publish?
Moreover, what is its politics? When WikiLeaks presents data on its web site, does it attempt to be accurate, complete, and fair? And, by the way, whom does WikiLeaks consider an oppressive regime? The USA? China? Iran? Canada? Will the advocates of the site publish secrets from all countries equally, or will they favor reports that support their favored causes or do damage to countries they dislike?
If their site makes a major mistake, to whom should the public complain? How?
If WikiLeaks was prepared to publish a detailed code of ethics that answers these questions (like major news organizations would), they'd get a bit more respect. Until that time, they are faceless cowards.
