He is the 506th person to die in a police shooting this year in the Land of the FreeTM
30,000 Americans have been killed this year in traffic accidents, and 100,000 by medical error. Somehow nobody is sharpening the pitchforks and lighting the torches over that.
You have to look at the specifics in each incident, and clusters of incidents to see if there is wrongdoing on the part of the individuals and institutions involved. Policing can be nasty and dangerous work. They tend not to interact much with the top 99% of orderly and civilized people, and the bottom 1% can be random, unpredictable and dangerous.
