On Tuesday, after three weeks of jury selection, another three weeks of testimony and 10 hours of deliberations, Derek Chauvin, a former Minneapolis police officer, was found guilty of murder in the death of George Floyd. The jurors found Mr. Chauvin guilty of all three charges: second-degree murder, third-degree murder and second-degree manslaughter. Sentencing will take place several weeks from now. Second-degree murder could mean as long as 40 years in prison. We look back on key moments from the trial and discuss the reactions to the guilty verdict. Guest: John Eligon, a national correspondent covering race for The New York Times.
