I saw an interesting study that plotted the lifecycle of shopping different malls and how bus stops effected the malls - negatively. Bus stops were supposed to bring customers and instead brought crime and violence.
That happened to a popular mall in San Bruno, just south of San Francisco. BART subway got extended from SF south to San Bruno parallel to the Tanforan Mall. Crime skyrocketed as black chiefs rode the subway from Oakland to San Bruno and committed assaults and thefts at Tanforan Mall. The mall recently announced it is closing, and most stores have left. A private company is taking over the property for building a private business park.
