Most of you do NOT know what goes on through the soldiers minds. You have no idea the amount of stress that goes upon them.
Yes, the people shouldn't have died, but it wasn't entirely the soldiers fault. They were in a hot zone, and had to make judgment.
In war, unfortunately, it's shoot, or be shot at. These guys did their best trying to see if they really were terrorists. It's not like us right now watching this video - we can see a pattern now that we can rewind the video over and over again. If you hesitate at a time where those are really terrorists, you won't breathe a next breath within the next few seconds after they blow you up with an explosive. It HAS happened many times before.
