I think it was in Denmark that people vomited, passed out and left the room as the videos were being shown.
I have seen many of them - fingers being sawed off of a child as she was taped screaming. A decapitated head being kicked around like a football. Lots of beheadings. Some fingers being shot off.
The child in the above video, fyi, was about 6 and kidnapped from her bedroom in Moscow. Held for ransom, finally returned with many missing fingers. They tried to bring her here to the US to talk and we denied them the opportunity. Her father was a famous radio personality in Moscow.
Once they had blown up a Russian soldier transport, the chechens would go and pick at the dead bodies and hold up parts on a stick. I saw it often on Kavkaz.
It is in fact the chechen culture which promotes violence and killing. The stories they read to their young children are loaded with things like impalings, etc.
