a few questions
Who ratted on the bank robbers? Was it the arms guy they arrested? Did Coyle not know that Dillion was suspicious and going to kill him? Powerful performance by Mitchum, amazing.

It was Dillon. Jackie (The Arms Dealer) had no idea about the bank robbers only that the guy he was selling to was buying alot of guns. For that matter, though Coyle knew what they were doing, he had no idea of where and when. Dillon somehow found out and leaked it.
