Why did Captain Browning...
Spoilers for those who didn't watch the film.
Why did Captain Browning not kill James Quinn and instead let him go?
Browning had a steady IRA contact in Boyle, a reasonable and seemingly well meaning man. Boyle asks Browning to kill Quinn, an upstart who killed the British soldier in the beginning of the film. But instead of pulling the trigger on Quinn, he tells him to kill Boyle, and intends to enter into a working relationship with Quinn. Why would he do that?
Is Captain Browning himself a triple angent then? Is he working for the IRA? Or is he a straight unionist, but for whatever reason he would prefer to have Quinn in power over Boyle at the IRA? Is he simply playing one against the other and doesn't care which one lives?
I read an interesting comment in another thread on this board on the subject, by user billyblackwood:
"The Brit intelligence officers were not corrupt, maybe cold hearted though. They had a job to do as soldiers, and that was disrupt the IRA by supporting the younger and more reckless IRA members. The old guard IRA were not as radical, but much more organized and dangerous to the Loyalists. The Brits wanted to wipe the IRA problem off the map in northern Ireland. What better way than fighting a bunch of inexperienced kids? Unfortunately the plan backfired on them "Bloody Sunday 72" and the rest is history."
Finally, there's this one part in the plot sypnosis for this film's Wikipedia entry that offers its own opinion on a related scene:
"Sean hesitates, and within this time Browing's men arrive and Leslie manages to shoot down Sean; however, it is revealed that Leslie is, in fact, an IRA double agent and was responsible for supplying a faulty bomb to the Loyalists in the pub, and since Hook has witnessed him, he continues to strangle Hook."
I think that's just plain wrong, right? I don't think the bomb going off in the pub was intentional, or that was what Leslie intended. He wants to kill Hook because he witnessed the bomb, yes, but I don't see any evidence in the film indicating that Leslie is an IRA double agent.
