You know that bullet experiment he did in the beginning? It wasn't until I took a forensics course that I knew what he was looking for. In ballistics, they look for the scratches on the bullets that appear after it's been shot. Bullet spin, as you know and the patterns are always unique to each gun. So the patterns on the bullets didn't match.
