“Self-defense” is how white people get away with murder. It is a textbook example of a “race-neutral” concept that has been applied with deep prejudice against Black people. It doesn’t matter if the Black person was armed, unarmed, strong, weak, fast, slow, or just walking home with some Skittles. If a white person kills that Black person, they always have a chance to “get out of jail free” by claiming self-defense.
