O.V. Catto: Hero
Here you have a guy, a black Republican, who was pro-military (he was a major in the Pa National Guard), pro-handgun (when he needed one he went and bought one) pro-education (he read Greek and Latin and studied higher mathematics) was pro equal rights (not the affirmitive action sort) and was assassinated by a racist who was abetted (and not convicted) by Philadelphia's Democratic political machine.
The guy's life story would make a great movie. But don't hold your breath waiting for it. He was, after all, a Republican.
