American blogger Joshua Landis writes that the perpetrators of the February 14, 2005, Hariri assassination may never be tracked down. “His (Seymour Hersh – an American Pulitzer Prize winning investigative journalist and author) sources at the UN tell him there is no evidence against Syria yet. That the Hariri killing was very carefully planned and executed, and that we might never find out who ordered that assassination,” writes Landis.
