was killing police officers in apartheid South Africa justified?

No, No, No, No, and No.

I assume this was a response to John Dibbles post above yours.
That means you would not kill to defend your own life or your family, or to prevent genocide. Given that we have murderers, mass murderers, and Hitler wannabes still alive in the world it seems like folks with your attitude would be eventually removed from the gene pool.
