The photograph has traveled through social media sites and articles, touching hearts while evoking memories of a racially charged, not-too-distant era in Hall County’s history. It shows a young child, dressed in white Ku Klux Klan hood and robe, touching his reflection in a riot shield carried by an African-American Georgia State Patrol trooper during a rally in downtown Gainesville on Sept. 5, 1992. The now-retired trooper, Allen Campbell, with his hands firmly planted on top of the shield, is staring down at the child, no particular expression on his face.
