Eftersom han bytte sidor.
Jedburgh anställdes för att "hantera" Craven men gillade honom och så låt honom undersöka av egna skäl.
När det gäller senatorn ... försökte han "snurra" händelsen till en positiv och Jedburgh var inte med om det ...
Jedburgh, who is revealed to be suffering from a terminal illness, meets with Moore, the Senator (for whom he had been working) and the political advisor who assigned Jedburgh to eliminate Craven.
He listens to their suggestions as to how to play the Northmoor incident in a positive light. He tells them that he is done and then suggests an assassination attempt on the Senator should be the feature story, to drive Bennetts death out of the tabloids.
They are happy to go along with the story until Jedburgh tells the senator that he is on the wrong side of the equation. Jedburgh then pulls out his gun and shoots all three men dead.
