Together Brothers (1974)

In a poor neighborhood in Galveston, Texas, a gang of teenagers sets out to solve the murder of a well-liked beat cop before the killer comes after the only witness, the five year old brother of one of the members. It’s an interesting blend of Blaxploitation and amateur detective mystery that is unique in the young age of the protagonists. The last act shows that the cop, while good to the youths, was not always kind to other disenfranchised groups which shines an important light onto other unfortunately more acceptable prejudices.
