Gangs ruled the streets, political corruption flourished, and riots frequently erupted, making the city a symbol of urban chaos. The violence and squalor of this era rivaled even modern crime waves in scale and intensity. As PBS details, Five Points became a cautionary tale, influencing how America viewed and addressed urban disorder.
