Standing outside the state Capitol on the morning of March 11, 2005, I knew there had been a tragedy. A cacophony of sirens, circling helicopters, police motorcycles roaring up sidewalks and people running in various stages of panic were some of the images seared into my memory. By the end of the day, I would find out that four decent, hard-working Georgians had been callously gunned down and killed by one man.
