This is a WAR...not a weekly television series like CSI.

Link to first MSM story (at least that I have seen).
Actually, I do believe they are using forensics teams. Remember the whole Zarqawi issue. They had his DNA & fingerprints on file that they had got from previous places they had raided.
If you send a forensic team, then if these people are captured by the Iraqi governmetnt (or detained as possible terrorists), they can be identified and the Iraqi Government may see fit to try them for their crimes.
It is war, yes, but this enemy does not wear the uniform that can be easily identified. They are terrorists.
Also, the FBI has a standing order to seize any terrorists anywhere in the world...
It is also my hope that taking such action would be a deterent from such cowardly activity as these terrorists performed by executing our soldiers.
In the Battle of the Bulge, German soldiers machine gunned newly captured US Troops.
Would we have been justified, if after the war, to bring such criminals to justice - when the United States occupied Germany?
