George Floyd's death 'absolutely preventable,' doctor says in Chauvin trial

The trial of former Minneapolis police officer Derek Chauvin on murder charges is entering its third week of testimony. The prosecution is nearing the end of its case, and Chauvin's defense is expected to begin presenting its case this week. Prosecutors have been focusing on medical experts as they try to prove that Chauvin's actions killed George Floyd. Chauvin held his knee on Floyd's neck for nine minutes and 29 seconds on Memorial Day last year.
