S.P.I.T.: Squeegee Punks In Traffic (1970)

The narrative unfolds from the point-of-view of a single character named Roach. As part of the filmmaking process, he's been given a camera to document his world. The footage he gets is urgent, because there's a war against squeegee kids. This documentary is from the point of view of the kids themselves, in order to provide alternative voices. Roach's camera is positioned behind "enemy" lines: living in derelict buildings, squeegeeing for money, being hunted by police.
