I understand that we must treat our enemies with certain standards...but rule of engagement in war?
Please read "Lone Survivor" the story of operation redwing....pay attention the the 4 seals debating and voting on killing 3 afg "farmers". The debate was ...kill them and risk being charged as murders or let them go and risk them telling you are there. The seals let them live and paid dearly for it.
All american's should read this book. It is very revealing about how we ask our military to do things with their hands tied by ROE's.
I'm not sure I understand your point strolling. Are you saying those soldiers should've killed those three people? even if they were unarmed and non-military? if that is what you are saying...wow... that's frightening.
Rules of engagement are what separate US from the terrorists.
