We can all guess the pressure these people were under, but they are supposed to be highly trained professionals who should take responsibility for their actions: if they f*ck up, they should 'fess up not cover up. And if they deliberately target civilians for kicks or ego or whatever, they've no place in the armed forces and should feel the full force of the law. The point is (or was), our forces were in country supposedly trying to pacify elements of the population and try to show we are the good guys - if we simply act like our adversaries, then what's the point in being there?
