Whenever an Afghan civilian is wounded or killed by Coalition Forces, everything stops. It's a big deal. The news reaches General Officer level very quickly. Maybe even to the White House.
When an American cop or SWAT team wounds or kills Americans in their American homes in the middle of the night? Meh, no big deal.
I've stated before that the US military has stricter Rules of Engagement for the Taliban than cops have for American civilians.
That is truly tragic.
