Very much true. We can speculate about what happened but we really don't know. We weren't there, we haven't been there, and thank GOD none of have to be over there in that mess.
This guy could of had an altered mental status from not only post-tramatic stress...but stress still going on! I saw the video and was it was very disturbing...but we just can't say anything because we were not there for the past 8 days.
In a perfect world, no one would ever kill anyone else...but this world isn't perfect and things do happen like this in war. I feel bad if the man that was shot point-blank was innocent, and if so then an investigation is going to take place (and it already is.)
