When he left for his overnight shift, police Sgt. Greg Moore would assure his young son Dylon he’d be OK. Because he was Batman. “My dad was the best … He was always there for me,” Dylon wrote in remembrance of his father, who was shot and killed Tuesday in the line of duty. The 12-year-old boy was there for his dad Saturday, along with thousands of others, at a memorial service to remember the life and service of the Coeur d’Alene police officer. The gymnasium at Lake City High School, where Moore once was assigned, was packed with police officers and emergency responders from across the Northwest and as far as Los Angeles and Chicago. They listened as friends, family and colleagues recalled Moore’s wit and good nature, his leadership and commitment to serve, and his devotion to his children.
