 Like other Detroit street gangs, such as their Westside Detroit counterparts in the late 1970s; the Nasty Flynns (later the NF Bangers), and 7 Mile Killers or 7 Mile Dogs or the drug consortiums of the 1980s such as Young Boys Inc., Pony Down, Best Friends, Black Mafia Family and the Chambers Brothers, the Errol Flynns grew out of the racial and economic unrest that transformed Detroit in the late 1960s and 1970s.As people and capital left Detroit for suburban communities, the city's social and economic infrastructure buckled, leaving the community fractured and impoverished.As the murder rate soared to the highest in the United States, and the city became increasingly viewed as dangerous and in perpetual decline, gangs began to seize territories.
