Crime Busters (1977)

Through an improbable series of events and an impossibly bungled supermarket hold-up, down on their luck con men Matt and Wilbur find themselves working with the Miami police force.

As they patrol the streets of the city, their main job becomes trying to break the hold of the city's street gangs, including one group of teens in old movie-gangster style clothes, led by a kid named Geronimo who dresses in full Indian warrior regalia.
