Derek Chauvin trial: what we've learned after the first week

Chauvin kept his knee on George Floyd longer than originally thought and witnesses described feelings of guilt

The trial against Derek Chauvin, the white former police officer charged with murdering George Floyd in Minneapolis last May, began in earnest Monday and lasted all week.

Floyd died after Chavin kneeled on his neck for more than nine minutes during an arrest. The public responded to Floyd's death with mass protests across the US in what became the largest US civil rights movement since the 1960s.
