You have to watch this video, it is truly incredible--and will be the subject of many a talk show tonight, beginning with MSNBC's Dan Abrams at 6 pm e.s.t. (Mickey Sherman guest hosting for vacationing Dan who returns Wednesday.)

It is also now the subject of a police probe.

The video is of four to five cops surrounding a teenager on the ground who does not appear to be resisting. One officer picks him up and slams really slams his head into the hood of the car. Another cop punches him in the head. The video was taken by tourists. The cops? From Inglewood, CA. (LA) The reason for the arrest? A routine traffic stop. The driver was found to be driving with a suspended license. The passenger, who allegedly got into it with the cops, was the attacked teen. Immediate sanctions? None, not even suspension or administrative leave.

Let's follow this one.
