It will have to meet very strict standards of proportionality; given that the target is a single person, it will be difficult to justify any injury to innocent bystanders. So the targeting must be undertaken with great care; collecting information about the targeted individuals, their schedules, their whereabouts, their families and neighbors, is critically important, and if it involves risk for agents in the field, the risks must be accepted before the killing can be justified.
