What type of ballistic expert did Hinton tell Stevenson he needed?

Hinton told Stevenson that he needed the best ballistics expert there was. The expert could not be a woman or someone from up North. The expert needed to be a Southern man, preferably white. He needed to believe in the death penalty. He had to be the best of the best and someone who had taught the State's guys. The expert needed to have every reason to want to see Hinton die if Hinton was guilty, but someone who would be honest. The expert had to be an honest, racist, Southern, white expert.
