In this clip from "Battle for the Holy Land," Israeli commandos have set up a late-night ambush targeting Palestinian gunmen believed to be planning an attack on Jewish settlers. Using thermal night-vision cameras, the commandos spot -- and shoot -- a man approaching the settlement with a gun. An Israeli commander discusses the policy behind this tactic: "The moral question -- do you just kill a man with no trial? ... Do you take out a ticking bomb, kill him, or do you try to arrest him?"
