In the opening scene of the 1973 movie “Serpico,” I am shot in the face—or to be more accurate, the character of Frank Serpico, played by Al Pacino, is shot in the face. Even today it’s very difficult for me to watch those scenes, which depict in a very realistic and terrifying way what actually happened to me on Feb. 3, 1971. I had recently been transferred to the Narcotics division of the New York City Police Department, and we were moving in on a drug dealer on the fourth floor of a walk-up tenement in a Hispanic section of Brooklyn. The police officer backing me up instructed me (since I spoke Spanish) to just get the apartment door open “and leave the rest to us.” One officer was standing to my left on the landing no more than eight feet away, with his gun drawn; the other officer was to my right rear on the stairwell, also with his gun drawn.
