no, its a conpiracy theory if and only if you can plausibly explain away all of the above stated inconsistancies. Until you can, its an open question.
What the media should be doing is informing people of these discrepancies, and maybe even *gasp* doing their own investigation. People have a right to know that there is something other than the official story, and that its has some pretty solid backing. You know, the good old two sides of the story.
Have we realy slipped so far in our expectations of the media, that we can now accept that their job is simply to tote the party line? The media, as an institution, is immensly important, their job is to question the status quo. But these days, its like the government and media are hardly seperate entities.
Keep in mind, that media corporations have hardly any national ties, so you shouldn't expect private news outlets in France to be owned by a Frenchman, or to reflect the mentality of the French people. For example, Rupert Murdoch, the US media tycoon (and staunch Republican) controls pretty much all of Australia's media. I don't have the exact figures, but he has most of the daily newspapers, and large chunks of TV and radio. So, Australians get the same news as Americans, with the same spin. I don't see why the same could not apply in France of Germany.
There is simply too much thats wrong with the official story of Nick Berg's death to accept it on blind faith. So, there should now be an investigation (not governmental obviously) in to these claims. That has traditionally been the role of the media, but..well....
