I agree that inquiries always go by human rights of the suspects (untill convicted) assuming that interrogators would extract more information by keeping such people than by eliminating them fast. In such cases the following should hold true:
The terrorist has no human rights; he loses them the instant he points his gun at humanity. He is not a signatory to the Geneva Convention and international laws of war should not apply to him. Since he chooses to live by the gun, he deserves to die by it.
