Massacre in Haditha

Here is a bbc report about the alledged murder of 15 civilians in Haditha, after an IED killed one American soldier. These marines I think already suffer from post traumatic stress. Observors said the soldiers went on a "rampage." We put our troops in situations like this, and when they flip out we prosecute them. I know killing civilians is wrong, but put myself in the place of the soldiers, I wonder if i would have acted differently. When does someone just snap? There can be no justice in this case: innocent people were killed, and to prosecute the soldiers won't bring them back. These soldiers need counseling. Of course its a political problem: we can't NOT do anything because that would undermine an already embattled Iraqi government. More sadness and tragedy from Iraq.
