The moment a group of nurses laughed as a World War II veteran died in a Georgia care home.The nurses were meant to be fixing an oxygen mask onto 89-year-old James Dempsey after he called for help saying he couldn't breathe. But a surveillance camera captured them laughing as the breathing machine failed, and Dempsey fell unconscious, and records show they waited an hour to call 911.One of the nurses is seen laughing so hard she is doubled over Dempsey's deathbed.Initially, Dempsey's family in Woodstock, Georgia, thought he had died of natural causes in Northeast Atlanta Health and Rehabilitation Center in 2014.However, his son Tim had promised they would install a hidden camera when he first moved in there as he feared mistreatment.Weeks after Dempsey's death, Tim reviewed the footage - and what he saw sparked a three-year legal battle.Despite watching the video in court in 2015, the nurses kept their licenses, until now.
