For decades, mobster Angelo Roberts wielded terrifying authority as the most omnipotent organized crime figure in the Chicago underground. Moreover, as the head of the Four Corner Hustlers gang, Roberts also clocked in as one of the youngest gang lords in the city's troubled history. The Four Corner Hustlers netted innumerable enemies during their reign, but perhaps none more trenchant than the Chicago Police Department - an organization against which the Hustlers waged a no-holds-barred territorial war for control of the streets. Shabazz's documentary Angelo Roberts: Friend or Foe? etches out a portrait of Roberts's rise to power and his brutal reign as a mafia kingpin.
