A guy is driving in South Africa during apartheid and speeding. He gets pulled over. He then notices that the cop in question was actually earlier enforcing apartheid on blacks. So he pulls out a gun and blows the cop away.
I vote yes. In fact I'd say that simply killing police for no reason at all in South Africa during apartheid was 100% morally justifiable. If you were a cop in South Africa during apartheid, you were a disgusting excuse for a human being. Period, no exceptions;.
Well considering one of the friend of Mandela is one of his own guards, I think you netter start making some.
