It's sort of pointing out that the media in France is constantly showing videos of black or east african descent commiting violence. It doesn't seem to make a judgement on them, which is where the controversy arises. They don't get their "comeuppance" as it were.
The voice at the end of the video says something like "you like to film that then, son of a bitch?"

That said, it's very much taking ideas from Aphex Twin's Come To Daddy and Prodigy's discarded Hot Ride video.
Which isn't a bad thing. Both are excellent, and so is the Stress video.

Popjustice have it linked to on their news page.

Makes that Prodigy video look like Mary Poppins
