Arm would be the most logical choice, if they didn't decide that i38x and amd64 weren't enough.
Hows about ix86? Or better yet, x86!
The video clearly shows them shooting at the people who arrived to help a wounded victim (identified by Wikileaks as one of the Reuters employees). However, when asking for permission to fire on the new arrivals, the American gunship crew repeatedly said that the people were "collecting bodies". But they weren't "medics" from what I could tell. They were just some passing civilians, trying to help a wounded man.
It seems to me that at the beginning of the video (~4:15), the guy peeping out from behind the wall is holding something long and thin aggressively. I can see how the way that he keeps popping back and forth could be construed as him trying to hide/get a better shot. Can anyone else explain what this guy might have been doing?
Today is a good day for information-gathering. Read someone else's mail file.
