Sorry, but if there's 190 Taliban gathered there, out in the wide open? Hose them down with a couple of AC-130s and then drop some GBUs to see how far the body parts bounce.
In World War II we gutted the hearts of some of Europe's greatest and oldest cities and killed hundreds of thousands of civilians as collateral damage. We killed a hundred and thirty thousand in Tokyo and made a million and a half homeless IN ONE NIGHT. War is a nasty, unpleasant, horrible business. But when it is fought, it must be fought to win, and that means civilians will unavoidably die.
The bombing of Monte Cassino comes to mind. Christian Monastary or not, that's where the nazis were and we took them out.
Re: AC-130s: To be fair, a C-130 has a high cruise speed of 330 knots. It would have taken several hours to launch them and get them to the site of the funeral.
When we killed tens of thousands of germans or japanese in a single raid it wasn't "collateral damage". It was done on purpose. It was total war, and civilians were targets.
