Nobel Peace Prize winner was a murderer (updated)

Well, it took only 33 years but our very own State Department has finally admitted that a Nobel Peace Prize winner, Jimmy Carter's bestest friend, honored White House guest, leader of a great, peaceful nation, worthy partner in peace and genuinely all around nice guy was gasp! shock!  actually a murderer!  And more!
Yep, according to a finally released declassified State Department document
The Khartoum operation was planned and carried out with the full knowledge and personal approval of Yassir Arafat, Chairman of the Palestine Liberation Organization (PLO) and the head of Fatah. Fatah representatives based in Khartoum participated in the attack, using a Fatah vehicle to transport the terrorists to the Saudi Arabian embassy.
Wow! Coulda fooled me.  Talk about hiding in plain sight.

Powerline details its years' long efforts to get the facts on the Cold River operation in which Arafat arranged the assassination of two US diplomats, how the Department of State lied about the record and covered for him and why the State Department has earned our  distrust .
[T]his whole incident illustrates why most conservatives have so little confidence in the State Department. The Americans who were brutally murdered by Yasir Arafat's thugs were State's own employees. And yet, for years the department covered for Arafat. Why?
