There isn't a single circumstance where someone should be praised for killing someone that didn't have to die. The idea that killing ever warrants praise is really insane and speaks to an impulse that we can reasonably be the arbiters of whether people truly deserve to die. You're literally sitting on this MMA forum typing that a guy getting shot and killed was justifiable because someone thought he was a burglar. You said above that these guys were heroes and more people should cheer them on because they stood up for their neighborhood. How does two armed men chasing an unarmed man and ultimately killing him equal heroism? Why even bother with the rule of law? Why are they "citizens" and he's not even human, just a "criminal" in your words?
You cite the racialization of this story in news media, but you completely misstate the narrative. Most of the narrative has been why did this guy have to die and why was nothing done about it? Various pundits have opined that race played a role because race seems to have played a role in a number of shootings in recent years, though I would argue it's more of a class issue with race often intersecting, predisposing black victims to seem more dangerous than they actually are. And here you are rehearsing literally every argument. In fact, in this thread it is only you who is racializing the narrative, going even so far as to say where is white justice and where is white peace, when in every single case you cite, the perpetrators have been arrested and convicted of murder, unlike in this case. You say you're fed up and talk about "clean shoots" as if you're on the white team and black people are on the black team and that is in itself the essence of racism. You talk about crime in "black neighborhoods" as if neighborhoods just organically become black rather than being poor neighborhoods with black people disproportionately represented among the poor and often pushed there. You are reacting to the outrage of black people over the convergence between being born into these conditions and seeing other black people summarily executed on video with no legal consequences by saying essentially that he was worthy of nothing but death. Black people have said nothing more than that no, he deserved to live. That his life actually mattered. It's taken months of people in South Georgia advocating and pushing the DA to do more and pushing on social media and elsewhere to get the story picked up by mainstream media and really it took the video being put into wide circulation, which obviously wasn't an accident.
You can be justifiably mad at the media for over-amplifying a race first narrative, but as a Black person, I can tell you it's hard not to look at that video and have it not just slot into a long story with all the other videos we've seen of unarmed Black men being met with lethal force and nothing happening. In my personal view, fatal encounters are complicated and always tragic, for the dead and the living. No one should ever have to die for something they're suspected of doing. No one should ever be made to fear for their life by being confronted with lethal force unless they're attempting to do serious harm to someone else. This isn't a "clean shoot," or a "great job," it's a tragedy, and an avoidable one at that.
