In The Place Beyond the Pines, we saw that Avery Cross (played by Bradley Cooper) discusses the whole situation about his fellow corrupt officers with his father (Judge Al Cross). His father advises him on something.
After that we saw that Avery discusses it with Bill Killcullen (played by Bruce Greenwood). He asks him to accept his three requests.
After some argument Bill agrees and accepts all three of his requests. Why did he do that?
