Could Jackie Brown have turned the tables on Coyle?

When Eddie turns in gun-runner Jackie Brown (Steven Keats), he scores some points for himself with the Fed, Dave Foley. However, Eddie has been committing a crime himself by buying guns from Brown. It seems to me that turning in Brown could have back-fired on Eddie. Brown could have fingered Coyle as a gun buyer, as part of a plea-bargain to reduce his own sentence. He also could have done this to get revenge, because it is clear when he is arrested that he realizes that it was Eddie who set him up (I’m not sure why he didn’t also suspect the hippies).
However, I can also think of a couple of reasons why Brown would NOT have fingered Coyle. For one thing, he knows Coyle works with the mob, and he’s heard Eddie’s story about the knuckle-breaking. He might fear that he would suffer mob vengeance, even in jail. Also, perhaps there could have no plea-bargaining for someone selling machine guns—as Brown said, “That’s life in this state.”
It’s interesting that when he’s arrested, Brown says (thinking of Coyle), “I’ll take care of it myself.”
The Criterion DVD includes stills of scenes deleted from the movie. There is a still of Brown and Foley at the police station. It would be interesting to know what was said in that scene.
