Ben Norton, an indie journalist, was the first person I've seen breaking down how the video was edited: http://bennorton.com/dashcam-video-of-violent-arrest-of-sandra-bland-was-edited/

They also didn't release the full footage of her time in jail, -only the "moment where she was discovered" hanging in her cell.

I don't believe in the death penalty but I'm nearing the point where I feel it should be enacted in limited fashion, only used against employees of local or federal government that commit murder.
