ATLANTA — Judge Peter Cahill hardly slept during the six weeks he presided over the murder trial of Minneapolis police officer Derek Chauvin for killing George Floyd.

       Cameras in the courtroom broadcast the veteran Minnesota judge’s every word to a global audience. Outside, the nation waited nervously for the outcome of a slaying that galvanized the movement for racial justice.

       “When you’re in a high-profile trial, you feel the stress, you feel the pressure even if you’re not reading the papers,” he told an audience of judges last year at The National Judicial College in Reno, Nevada.
