The murder case against former officer Derek Chauvin in the death of George Floyd went to the jury on Monday in a city on edge against another round of unrest like the one that erupted last year over the harrowing video of Chauvin with his knee on the Black man’s neck.

The jury of six white people and six people who are black or multiracial began deliberating after nearly a full day of closing arguments in which prosecutors argued that Chauvin squeezed the life out of Floyd last May in a way that even a child knew was wrong.
