When gangs have their own wikipedia page, I’m not so sure that “normal” people can do much about them. Perhaps, like in Mexico, they will win.
“The Four Corner Hustlers or (4CH) is an organized street gang originating on the West Side of Chicago, Illinois. Together with the Vice Lords, Latin Kings, and Black P Stones, they are one of four dominant Chicago gangs involved in drug distribution, accounting for 84 percent of gang membership. Outside of Chicago, they are particularly found in Maywood, Illinois and the surrounding community.”

Another reason I never click on wickipedia.
