Of course some, even many of these are justifiable. Without even reading the stories, I would guess about 75% are actually justifiable, 15% - 20% are somewhat justifiable, and 5%-10% are not justifiable at all.
You could say those percentages are reasonable averages - ever. It would be a ridiculously foolish intellectual exercise to entertain the idea that ALL police shot inge are justifiable. There is no way that is an intelligent hypothesis given the amount of corruption cases that have actually made it to court or media news (not counting settlements, and cases swept under the rug.)
So, we know unjustifiable, abuses of police power happen. I think 5%-10% is a generous estimate.
So, the OP is posting information with general statistical and demographical information. We can look these people up to see the real story.
The problem of "not" posting something like this despite its generality, and the reason why it is shocking enough to post, is because as we assume those percentages stay the same, as the number increases the number of unjustifiable shootings statistically increases.
By May, for the police have almost killed 400 people means 20 - 40 of those incidents were statistically unjustifiable. That is a lot of unjustifiable shootings (one is honestly too much, but I know that I would be too idelistic to assume cops won't unjustifiable use and abuse their force.)
Last year it was almost 1200 I think... that would give 60 - 120 cases of unjustifiable shootongs... the higher the kill count rises, the more statistically unjustifiable shootings you have.
And, it should also be alarming that cops must use their guns so much.
