To start with the moral basics, the officers who initiated force against Nichols, a 29-year-old father, and the others who joined in once the assault was in progress, had no apparent reason to believe Nichols posed any danger to them or the public. Judging by the body-cam video, the first officers to stop and approach Nichols's car were exceedingly hostile from the start. It would be wrong to say they escalated the situation — rather, they appear to be in high confrontational mode from the get-go.

Some might say that Nichols failed to comply with the officers' angry orders to get out and on the ground as they pulled him from his car. From the video, it looks more like Nichols was shocked and disoriented by what was happening. "What did I do?" he asked. He didn't strike the officers; he asked a question. I suspect that police culture doesn't cotton to such impertinence even when a suspect appears unthreatening. Yes, he ran away when he got the chance (and was soon caught and brutally punched and kicked again), but that was after being assaulted, tased, and pepper-sprayed. Watch the videos from the police body cams and pole-mounted surveillance camera for yourself. They're not easy to view.
