Your objective point is correct. The necessary facts are not provided.
However, it is a bit ironic to accuse the other forum member of bias without leveling the same charge against the many more posters who have expended many words explaining in great detail why it is not the police officers' fault.
The officers were the professionals on the scene. Since they killed a man who was (objectively at least) not a threat, they failed, and it is their responsibility to explain why that was unavoidable. It may well have been, given the dead guy's mistakes. Whether circumstances provide them with sufficient evidence to show that is impossible to tell from the video. The investigation will need to determine that. Until then, neither condemnation nor benefit of the doubt are appropriate.
I don't take lightly the fact that man was killed, whether he was a "known offender", "bad" guy, or a law abiding CCW holder. Those cops will have to account for their actions, whether that is in a criminal or civil court, administratively or within their own conscience.
My post was concerned with the stated belief that the officers would "get away" whereas another person (CCW) would be taken to task.
If neither condemnation nor benefit of the doubt are appropriate, then let's withhold both.
