Gangs have existed for a long time throughout history. Modern urban teenage gangs bring fear and violence to many large cities around the world. Gang members often come from similar backgrounds, whether ethnic, geographic, or sharing a common interest. Gangs can make a lot of money from illegal activities like drugs and gambling, allowing them to grow larger and become more dangerous every year in both small towns and large cities. A former gang member suggests offering hope to kids so they don't feel apart from society, otherwise gangs will continue growing.
