The retired Los Angeles police officer who writes about law enforcement under the name Jack Dunphy has penned a column analyzing the Tyre Nichols death for Pipeline.

Here’s an excerpt.

You’ve heard the saying that one shouldn’t ascribe to malice what can be explained by incompetence. In the death of Tyre Nichols at the hands of Memphis police officers, there is ample evidence of both.

An official autopsy report on Nichols has not yet been released, but a pathologist hired by Nichols’s family performed an independent autopsy and concluded Nichols died from “extensive bleeding caused by a severe beating.”

That’s exactly what it was, and in my judgment not a single kick, punch, baton strike, Taser activation, or use of pepper spray can be justified under the law. And while five of the involved officers have been fired and charged with murder, I believe it is the one I call Officer X who is the most culpable in the death of Tyre Nichols, for it was he who delivered the two kicks and five vicious punches to Nichols’s head that will likely prove to have been the fatal blows.
