Here is an interesting twist:
“England’s father, Carl, was fatally shot in 2010 by a black man who had threatened Carl England’s daughter. After tracking down Pernell Jefferson, the men fought and Carl England was fatally shot. Jefferson was not charged with homicide because an investigation determined he acted in self-defense.”

An investigation comprised of eye witness testimony and corroborating evidence at the scene said that Zimmerman acted in self defense too. But the National Lynch Mob scared Florida authorities into arresting him anyway.
Yes, the father killing thing is an interesting angle. The guy left to go get a gun and came back and shot the father.
