A suburban Minneapolis police officer who said she mistakenly drew her gun instead of her Taser when she fatally shot Black motorist Daunte Wright went on trial on manslaughter charges Wednesday, with a prosecutor saying Kim Potter had been trained how to avoid such deadly mix-ups but still got it wrong. Potter's lawyer, though, argued that she made an error. And he appeared to cast blame on Wright, saying all the 20-year-old had to do that day was surrender. "All he has to do is stop and he'd be with us, but he goes. She can't let him leave because he's going to kill her partner. And so she does Taser, Taser, Taser and she pulls the trigger, believing that is was a Taser," said defense attorney Paul Engh in his opening statement. Potter, 49, killed Wright during a traffic stop April 11 in Brooklyn Center in a shooting that was recorded by her body camera. The white officer resigned two days later. A mostly white jury was seated last week in the case, which sparked angry demonstrations outside the Brooklyn Center police station last spring as former Minneapolis Officer Derek Chauvin was on trial just 10 miles (16 kilometers) away for killing George Floyd.
