Among these is Marjorie Cohn, immediate past president of the National Lawyers Guild, who tells IPS: "Targeted or political assassinations - sometimes called extrajudicial executions - are carried out by order of, or with the acquiescence of, a government, outside any judicial framework." 

She cited a 1998 report from the United Nations Special Rapporteur that noted, "extrajudicial executions can never be justified under any circumstances, not even in time of war. Willful killing is a grave breach of the Geneva Conventions, punishable as a war crime under the U.S. War Crimes Act." And "This is not a war," she adds.
