Black South Africans must be a very forgiving lot.

BBC NEWS | Africa | Shock at SA lion murder acquittal

Forgiving? No, I wouldn't say that's the case although it does indicate that something is seriously wrong here. This is just one example out of several others of foreigners carrying out heinous crimes against africans on their own home soil with impunity.
I recall another case of another white farmer in SA who shot a man and pleaded before the judge that he had thought it was a baboon he had had in his crosshairs at the time (I think it was on BBC 's website).

There was also another, in Kenya this time, (actually still ongoing, I think) in which the son of one of the largest landowners ( a remnant of the colonial period) had shot and killed a black man. His plea being that the man had been a poacher (the pot calling the kettle black - I mean how did daddy come by all that land in the first place?).
In this third case and indeed all of them, one can almost hear the perpetrators think " They are only natives after all , ofcourse I'll get away with it." Although the landowner's son is said to face the death penalty but I must say that it will come as no surprise to me if he does walk away a free man at the end of it all.

And it is not just the Europeans, I have heard from Kenyan and Ugandan friends about the sort of treatment meted out by Asians to the blacks who work for them. In fact I heard that one asked a black worker to clean a table with his tongue.
There was also a case in Nigeria of an Indian factory owner who locked up his staff overnight thus preventing any chances of escape when the premises caught fire.
And then there was the case of the of the Chinese bakery owners in Abuja who kept their staff locked up under furnace like conditions.

But back to the topic at hand, the ruling must not come as a surprise as one must remember that most of the judges who held sway during the apartheid era are still around due to the 'sunset clauses' agreement between the ANC and De Klerk's government.

To make matters worse it is said that black SA's themselves have adopted a perjorative term for other black foreigners in their midst "Makwerekwere" (It was actually confirmed by one on a Nigerian online forum).
Now, the levelling of any strong feeling of collective dislike and the application of perjoratives by SA blacks at their fellow africans rather than at at those who do not belong there at all and who in the past have applied perjoratives to them and commited atrocities against them shows that there is indeed something wrong somewhere.
