Assuming journalist investigate stories is like assuming sheep are bloodhounds. Spoon fed bias reporters is a more accurate label for South Africa's mainstream news media. 

The truth of ANC leadership's lack of ethics have been evident since 1976 youth uprising where children were actively manipulated as front line combatants and brutal murderers, all the way through the struggle where civilians (mostly blacks) were targeted and right up to date with "revelations" corruption and state capture.

It's a misconception that ANC Leadership's morality has degenerated since "reported" grand days of the "heroic" struggle era. Leopards don't change their spots. Leaders who were seen as ethical struggle heroes don't suddenly become unethical public servants interested only in accumulating wealth and power at the detriment of the needy.

Media are captured by their own bias. Given a flimsy thread with apartheid or colonialism rhetoric, a reporter can be led by the nose to ignore the facts.
