If you want to have people stop ignoring the tape put it on the internet...the the networks will be forced to talk about it.
Is there a link to see the video online?
Here's NRO's explanation - I'm not sure I agree with it:
"The Daniel Pearl murder, the Nick Berg video, these visuals do remind us in ways mere wire stories, reporting pieces, and commentary can't. In the case of the Pearl and Berg videos, NRO itself never provided links to the videos or the videos themselves. In that same vein, we are not introducing this Abu Ghraib video to public access...
The decision we came to was to report this news — the existence of this horrid tape — graphically, but without showing the actual video. It's awful enough to read about. "
