I'm going to see if I can find in the CG where it says dogs can not be used for interigation. Just because I don't take the globes word for it. They've been know not to do homework before. If someone else finds it first let me know.
However, that's really irrelevant as TERRORISTS don't fall under the protection of the:
Adopted on 12 August 1949 by the Diplomatic Conference for the Establishment of International Conventions for the Protection of Victims of War, held in Geneva from 21 April to 12 August, 1949; entry into force 21 October 1950
But we knew/know that.
