Another shoot up in America

Tragic news this morning to read there has been another school massacre in America. It's the biggest death count yet for a school massacre, far bigger than Columbine.

Over on another blog I follow an interesting point has been made about the media coverage which today's incident is getting.

News works in mysterious ways
What I can't get my head around is the tendency for all news networks to clear their schedules when something like an American school shooting happens with a few dozen casualties. Incidents like that happen every day in Iraq or Darfur or Afghanistan or Chechnya and those barely cause a mention anymore on the airwaves. American lives are obviously worth many times that of a dead Iraqi or a Darfur genocide victim.
