United Nations Human Rights Council; Study on Targeted Killings
or arbitrary executions, Philip Alston
Summary
In recent years, a few States have adopted policies that permit the use of targeted killings, including in the territories of other States. Such policies are often justified as a necessary and legitimate response to “terrorism” and “asymmetric warfare”, but have had the very problematic effect of blurring and expanding the boundaries of the applicable legal frameworks. This report describes the new targeted killing policies and addresses the main legal issues that have arisen.
