I don’t think so; this cop was Asian-American, but those days are over. Reuters 2/11/16: “A New York City police officer was convicted of manslaughter on Thursday for fatally shooting an unarmed black man in a darkened public housing stairwell.”
If there was justification for the shooting, usually the cop is cleared (as he should be); this cop shot this guy for no good reason at all.
A white cop shot a black man in suburban Minneapolis, was charged with many of the same infractions this cop was charged with, and wasn't convicted. For every incident you mentioned there are many more where the cop is either not charged or not convicted.

"Justification" usually is summed up by the cop saying he thought that his life or the life of others was in danger. They're claiming that there was a loud noise that startled them so he shot. Officers have walked away for less.
