So, going back to Colin's argument, you do realize you're talking about remote controlled weapons on both sides. Apparently remote controlled weapons are not cowardly or at least more morally justified, as long as they're on the "right" side. So by extension, a tactic can rely on what cause it serves for justification. That avenue pretty much leads to "just warfare" being a matter of subjective point of view. Don't get me wrong, I don't at all agree with Colin's view that drone usage leads to a moral dilemma, as his position, if I read it right means the only "morally right" action in the world is impotency (since power is universally corrupts, yadda yadda). That said, it's important to recognize when you're calling out cowards for using tactics that are very much in your own "side's" arsenal. Regarding the scanner, I suppose the allegedly Iranian backed Iraqi insurgents feel they've really made an intelligence coup against the might American war machine until one of the guys huddled around the monitor says, "Hey, we can see our [house, cave, tent] on this! Oh, wait."
