was killing police officers in apartheid South Africa justified?

Perhaps, but you're saying it like that means a bad thing.  Name THREE countries that are prosperous growing countries with a healthy outlook on the future with a black leader.  Please do.

It would seem to me that the only countries to ever have a black leader would be African countries, most of which are already horrible places to live, so it's not exactly like we have a representative sample of black leaders to choose from.
