This is absolutely horrible. I have a side gig that includes working with police experts for Use of Force investigations, shootings, etc., that has included some pretty high profile cases. The defendants are going to be looking for experts at some point, and if they contact us, this is one we wouldn't touch with a 10-ft pole.
The part where he's calling out for his mom as he's getting beaten to death is completely heartbreaking. Those particular cops should burn, and I bet 95% of cops who see that video feel the same way.
