Nope, you are comparing apples and oranges.
The one accidentally killed someone and the other did so with intent to kill. No burglary crew in SA makes the "mistake" of killing, that's one of the reasons they are there in the first place, a bit of fun while they pillage. The only mistakes they make is to accidentally kill someone too soon or to foul up the burglary.
So no, in a honest comparison you are the one being a hypocrite here.
On a personal note I admit my bias where the one group still has benefit of the doubt left and the other needs to be rounded up and shot..... good thing for them I am not in charge of anything. I have zero sympathy left with SA's murder/rape gangs. What they do is pure evil not just stupidity, the fact that they happen to generally be stupid does not enter into it.
Until cops over there start helping such gangs as they do here I will still give them the benefit of the doubt.
