Most of the time this doc doesn't even have anything to do with the 13th amendment. Then why the title?

Besides that this is one of the most horribly shot/edited films I have ever seen. The mother of crossing the line, cutting from talking heads talking into the camera to them talking out of the frame at the edge of the frame. How does a director not see/change that?

Contentually this movie offers nothing one hasn't heard before (number of US prisoners, percentage of black inmates, etc).
