The poverty-stricken housing projects known as Cabrini–Green were constructed at the meeting point of Chicago's two wealthiest neighborhoods, Lincoln Park and the Gold Coast. After World War II the cash-strapped city began withdrawing crucial services like police patrols, transit services, and routine building maintenance. Lawns were paved over to save on maintenance, failed lights were left for months, and apartments damaged by fire were simply boarded up instead of rehabilitated and reoccupied. The balconies were fenced in to prevent residents from emptying garbage cans into the yard, and from falling or being thrown to their deaths. This created the appearance of a large prison tier or animal cages. Later phases of the housing development were built on extremely tight budgets and suffered from maintenance problems due to the low quality of construction. The local police and the city gave up on the area. Crime and gang violence were rampant.
About the only thing that changed over the years, was the ethnicity of Cabrini–Green's residents. In the beginning, the population was Swedish, then Irish, and eventually Sicilian. By the 1960's the population was predominately black. Poverty was the one thing they all had in common. In the 1990's, the city started experiencing another culture shift which triggered another change in Cabrini–Green's population. As the city's poor abandoned the projects, a paranormal population moved in and took over. Cabrini–Green became home for paras that didn't fit in well with the rest of Chicagoans. Many of them had an appearance that could never pass for human. The city wasn't ready to accept them. Finding jobs and housing was an impossible task. They faced harassment and discrimination at every turn, and no one in the city would do anything to help them. Others found it too hard to live by the rules of human society. They gravitated to Cabrini–Green, where they could make their own rules.
Boarded-up windows, burned-out areas of the facade, and pavement instead of green space -- all in the name of economizing on maintenance -- created an atmosphere of neglect and decay. The corridors of the buildings were littered with trash and the walls covered with graffiti. Elevators were broken and useless. Some apartments had their front doors torn from their hinges. The doors were simply leaned against the openings. Rat and cockroach infestations were commonplace. Basic utilities, such as water and electricity, often malfunctioned and were left unrepaired. Specific "gangs" controlled individual buildings, and residents were pressured to ally with those gangs in order to protect themselves from escalating violence. The city abandoned the area and didn't care what happened within Cabrini–Green, as long as it stayed in Cabrini–Green. The police avoided the area, leaving residents on their own.
