Write a summary of what all gangs in the 1960 had in common

What did gangs do in the 1960s?

By the late 1960s, the construction of public housing Chicago allowed gangs to consolidate their power in black neighborhoods, and the Vice Lords, P-Stones, and Gangster Disciples controlled the drug trade of the area. These and others emerged as "super gangs" with more than 1,000 members each by the 1970s.
