Murderers do deserve to be put away forever. But it doesn't happen very often in this country, does it?
So let's take young men who are shot at daily, whose lives are on the line, who probably saw a gun and MAYBE over-reacted.
Do I want them on the battlefield? No.
Do I want them to be punished for bad judgement? No
Do I think they literally spent 4-5 hours going house to house and forcing women and children to their knees and executed them? No.
I think if you took all the fire "incidents" after the end of "major combat operations," and---if true---look at this this incident as a %, it's statistically insignificant. THAT is the message that needs to get out.
