At the very beginning of the movie, we see Scottie vaulting across rooftops, struggling to keep up with the policeman ahead of him as he realizes that he is afraid of heights. He is, of course, suffering from castration anxiety. The ability to chase down criminals is important to his work, which is tied directly to his role as a male, providing for himself. If he is unable to perform adequately, it will signify that he is impotent. When he fails to save the life of the policeman who is trying to save him, he is effectively castrated.1
