The American people and the American military will never get used to civilian casualties. And we will - we will fight against that every way we can possibly bring our intelligence and our tactics to bear. We're not the perfect guys, but we are the good guys.

The first time you blow someone away is not an insignificant event. That said, there are some *******s in the world that just need to be shot. There are hunters and there are victims. By your discipline, you will decide if you are a hunter or a victim.
