fucking crazy.... people dead on the floor and fuck face is taking a video of it.. shmuck.. why dont you go check on the wounded.. moron
Because there is no point?
The only thing you can do is go to people still making some noice, and stop bleeding if it is there, nothing else. You can't touch/move anyone in a situation like this, there is no danger or any reason to do so. If the blast did not kill them instantly you have about a 3/4 hour gap anyway before the next batch of people start passing away and by then the qualified people to help have arrived.
I do agree on the "post a video to the internet" part though, rather tasteless but i bet the guy made many thousands of dollars with his tiny movie.
