The unseen scars of those who kill via remote control

Kevin Larson crouched behind a boulder and watched the forest through his breath, waiting for the police he knew would come. It was Jan. 19, 2020. He was clinging to an assault rifle with 30 rounds and a conviction that, after all he had been through, there was no way he was going to prison. Larson was a drone pilot -- one of the best. He flew the heavily armed MQ-9 Reaper, and in 650 combat missions between 2013 and 2018, he had launched at least 188 airstrikes, earned 20 medals for achievement and killed a top man on the U.S.' most-wanted terrorist list. The 32-year-old pilot kept a handwritten thank-you note on his refrigerator from the director of the CIA.
