Who??
Name some with a source please.
Please source the bounty info too..haven't heard that one yet, even at DU.
Regardless, go to reports like the report of General Ryder about how detainees are often innocents. They use the dragnet approach, rounding up many with the intent of sorting through later. That's why so many are released.
So we have a choice...
If we follow the suggestions of some on this thread (e.g., drowning all detainees), then we either are going to kill innocents, or require our troops to be use more discretion in who they capture. Personally, I don't want our troops to be handcuffed that way.
