One consequence of fighting a guerrilla war against an enemy with total contempt for the rules of warfare is that you find yourself slowly adapting his tactics to win. So it is no big surprise to learn this:
"Baiting is putting an object out there that we know they will use, with the intention of destroying the enemy," Capt. Matthew P. Didier, the leader of an elite sniper scout platoon attached to the 1st Battalion of the 501st Infantry Regiment, said in a sworn statement. "Basically, we would put an item out there and watch it. If someone found the item, picked it up and attempted to leave with the item, we would engage the individual as I saw this as a sign they would use the item against U.S. Forces."
No possibility of that tactic going wrong, is there? One dimension of committing to an indefinite occupation of Iraq, which means an indefinite war against Jihadist insurgents, is how their depravity seeps back into the US military. We've seen what has happened with torture and abuse. Even if it hadn't been authorized by the president, it's likely some of it would have crept in because of the very nature of the enemy we are engaging. Fighting this war without having it corrupt us is the great challenge we face. It gets harder and harder the longer we stay.
