By: Mike Glover NORMAN, Oklahoma - Booker Shackleford was the City of Norman’s first African American police officer and a hero to most people. For his four children, he was just dad. Marjorie and Michelle Shackleford grew up with what they consider the world’s greatest dad. "To me and our family, my dad was amazing. You know, he was just dad. He was a normal dad, but from the outside of the house, I personally didn’t realize how much of a big impact he was until we heard stories," Marjorie Shackleford said. Those would be about the challenges of being a Black police officer when Norman was a sundown town, meaning Black people could not be out of the house after sundown.
