Karen Read trial: Defense's full closing argument [RAW]

Karen Read's defense attorney Alan Jackson presents his closing arguments to the jury. Read, who is being retried, is accused of striking her boyfriend, Boston police officer John O'Keefe, with her SUV and leaving him to die in a snowstorm outside a house party near Canton, Massachusetts. The case has inspired true crime documentaries. Last year, a judge declared a mistrial after jurors said they were at an impasse.
