When I first heard about this video I avoided watching it. I still refuse to watch it. We (the US) are in a war. Sick stuff like this happens. Did people think accidents never happen? That only the bad guys die? Does anyone stop and think that the bad guys are actually people? I'm not happy about it one bit, but what did people expect to happen? It's why war needs to be avoided if it can at all cost. But don't act surprised when people end up dead.
I took a self defense class towards the end of college for kicks. One day a girl asked what he thought about carrying a knife for self defense. His reply: You bring a knife to a fight, EVERYONE gets cut.
