Kaylub Giamanco ran into his daughters’ Bend, Oregon elementary school last month, after spotting the gunman heading into the building. Inside, Giamanco says he saw the gunman struggling with a teacher, motivating the father of two to take action: “I didn’t want to hear what he had to say, he had taken lives.” In a network TV exclusive, Giamanco and his wife, Kelsey, share about the emotions of that day, how they’re speaking to their daughters about the shooting and how the incident has inspired him to change his career and help others. - @cbsmornings
