The End of the Affray: How The Football Factory's ending is just incorrect

I rewatched The Football Factory on Film4 last night. I don't harbour any real dislike for it as many do; elements of it are misunderstood and better realised than it gets credit for. I want to talk about its ending, though. You cannot end a film like The Football Factory does. I don't mean it ends badly. I mean it ends wrongly.
