It's not about gore, it's about psychological horror. I mean, listen to those people screaming and crying, that's like straight from "Apocalypse now" - "I...I...I cried. I wept like some grandmother. I wanted to tear my teeth out. I didn't know what I wanted to do." Desperation and horror.
There are a lot of videos from war in Chechnya, but the one that struck me the most was where a cameraman gets shot by a sniper and with a slight gasp he just says "Ah, he killed me! He killed me!" and then collapses. No tragedy, no struggle, just like pulling a switch. That was so simple and mundane, that it made me die inside.
