The only reason I can think of regarding the media is that the Russian government is keeping a tight lid on. What really astounds me is that the interest has dropped this low. There was a worldwide debate about these atrocities a few years ago but that apparently died down. It could of course be that no western countries have any financial interest in Chechnya.
Johnny, I believe the people who attacked the theatre in Moscow were Chechens, I may very well be mistaken. And not all of the visitors were Russians, and orse (IMO) there were several children in there.
