A not unreasonable motion. The prosecution witnesses went for a lot of emotional appeals and had some "damning" sound bites but they didn't present a consistent argument that it was Chauvin that caused Floyd to die. They started off saying the knee on Floyd's neck killed him, then when they realized the knee was on his back for a large part of the video they said well a knee on the back could have compressed his lungs and killed him. Those are not consistent cause of death theories and every expert who attested to that claim did so based solely on their armchair judgement from watching the video as opposed to an actual autopsy. At least one use of force witness for the state also said Chauvin could've used more force. This is an opening day argument from the defense. I assume they are making it with the full expectation they will still have to present the full defense argument. But a good way to at least move the jury in their direction.
