And our Conduct will be reflected in the Arab world , where it will be use to create converts to there warped ideas. Basically if you want to feed them Propaganda to use , then at least you better know that is really all you will get. The "info" you gain will be lies, not verifiable, quickly outdated as they adapt, and even if true, you would not know if it was. It could even be used to help there own cause, you get them torture them a bit, and they tell you of a fake plot...you react to it, and the nation goes into a panic again...and there is nothing....They just got another small victory.
Also just because you distinguish them as Al Qaeda, does not mean that when we catch them and then do what ever to them, that those images and views of what we do, would not carry over to a Army as well. If you watched the US cutting of fingers using drills on Taliban guys etc, and are in the Iraqi army ....do you really think they will be thinking...well I am sure they will not do that to me? Nope.
Also I think its time the US stoped this idea that we can fight wars, call them wars, use US troops...and then act like when you get some they are not POW's, but also not under US law, so therefor we are free to do what ever we want with them for as long as we wish. What Precedent does that set to the world...They are terrorist....why? well becuse we said so....its not a real good argument.
The IRA did not use Uniforms, but was after much pushing given POW Status by the UK. Random but just a point to be made.
