Killing Kamal Jumblat

In 1977, when the Syrian regime killed Kamal Jumblat, they used a car with an Iraqi license plate in order to point the fingers to their enemy in Iraq.  But they left in the trunk cassettes containing songs for the Syrian Ba`th.  How do we know this?  Because the car broker down as the killers were fleeing the scene, so they had to park it at the side of the road and abandon it.  They had to hitchhike their way back to safety.  True story.
