It wasn't a standard 200 round AK mag it was one of those plastic double drums (I'm not sure what they're called) I'm a 1 shot 1 kill guy. It wouldn't be difficult for one guy to do that much damage in that time... It would be impossible! I was a sniper and I'm not that good.
I've been following the story and I'm hearing chatter about a shooter in the crowd. There's a good video on Y-Tube by Jay Myers Documentaries... it has a lot of esoteric stuff, but other than that it's pretty concise.
