Task: Question Answering
Input (English): Passage: In 1997, Luke Glanton is a motorcycle stuntman. In Schenectady, New York, Luke reunites with his ex-lover Romina Gutierrez, who is dating another man named Kofi Kancam. Luke discovers that Romina has a baby son named Jason that he fathered which she never revealed to him, so Luke quits his job to stay with Romina and their son.
Luke begins working part-time for auto mechanic Robin Van Der Hook. Luke asks Robin for more work and Robin who can't offer it legitimately, reveals his past as a successful bank robber and offers to partner up for a few robberies. Skeptical at first, Luke decides to take Robin up on his offer after planning and setting up their first job. They successfully pull off a few heists by having Luke rob the bank at gun point, use his bike as a getaway vehicle and ride it into a box truck driven by Robin. 
Luke uses his share of the money to get closer to Romina, and visits her and his son more often. Luke takes Romina and Jason out for ice cream, and the three ask a passerby to take a photo to capture the moment.
Luke and Kofi, who objects to Luke's presence, get into a fight, and Luke is arrested after hitting Kofi in the head with a wrench. After Robin bails him out of jail, Luke insists on giving his robbery money to Romina to give to Jason when he's older. Luke insists on resuming their bank robberies, but Robin objects, and the two have a falling-out that results in Robin dismantling Luke's motorcycle. Luke robs Robin at gunpoint, and uses the money to buy a new bike.
Luke attempts to rob a bank alone but fails to properly plan for the job and is pursued by police. Luke is cornered in the top floor of a house by rookie police officer Avery Cross and calls Romina, asking her not to tell Jason who he was. Avery enters the room and shoots Luke in the stomach. Luke fires back, hitting Avery in the leg, but falls three stories out of the window to his death. 
Question: What is the profession of the person who shoots Luke?
Output (English): police officer.
