As such, it’s possible that Jeffrey Wright’s James Gordon is still a detective at this point, or perhaps has made it to the rank of lieutenant or captain, similar to Gary Oldman’s Gordon in the Dark Knight trilogy.
While it’s not an origin story, Robert Pattinson’s Batman will still be relatively early into his crimefighting career during the movie.
So while he would still be in a position to help Batman out, he wouldn’t be the one calling the law enforcement shots across all of Gotham City.
