From the article:
'Psychologists and criminologists called the reluctance of witnesses to involve themselves the “bystander effect,” or the “Kitty Genovese syndrome.” Studies discerned a “diffusion of responsibility,” finding that people in a crowd were less likely to step forward and help a victim. Some communities organized neighborhood-watch patrols. In New York, an emergency call to the police was simplified later in 1964 — from dialing “O” for operator or a precinct or a borough headquarters, to a central police number. The unified 911 system was not established until 1968.'
