This is the problem with selecting a single element of detail out of a body of data and using it to make an argument that completely ignores the rest of the data.
If you look at the data in its entirety you will realise that no race, sex, or whatever is immune to being killed by the police... especially if you charge at the police with a knife or point something that may look like a firearm at them... the police will shoot you no matter who or what you are - this is just Darwin's theory of natural selection in action - weeding out the stupid gene so that it hopefully does not multiply, regardless of race.
However, if you look at all the data... not just the part that support the argument that you have already decided you want to make... all of the data... you will see that from time to time innocent men and women, black, white and everything in between, are sometimes killed needlessly by police. Sometimes it is an error - a civilian crossing the street in the middle of a shoot out with criminals - sometimes it is a cop who has had a bad week and that innocent person just happened to in the wrong place at the wrong time when the police officer lost control of their faculties. Regardless of the reasons, if you look deeper into the data... once again all of the data at the same time, not individual strands separated from the rest of the data... you will see that all too often, when this happens... when an innocent person is killed by the police... there is a disproportionate probability that that innocent person is going to be a black male than any other race or sex.
This is not a point of view to be debated... this is a matter of fact as evidenced by the publicly available data - we can debate why this might be the case, but not whether or not it is happening... that would be disrespectful to all he innocent people, of all races, whose deaths at the hands of the police make up the data we are discussing.
Now lets go out and celebrate one more gangster, murderer, rapist, etc who was stupid enough to go toe-to-toe with the police... and is now six feet under pushing daisies. We should not forget that sometimes the officers may not have had an alternative option that would safeguard life and property at the time or may have already exhausted non-lethal options at the time they took the lethal action.... sometimes.
