I randomly clicked on three of the links.
One was a man who a child wittiness claimed had his hands up as he got out of his car, but the cops claim to have found a gun on the scene. So, unclear as to justification.
The second was a man who was beating a woman, took her hostage and fled the scene when cops arrived, the car died as he tried to enter the freeway going the wrong direction, then he began strangling the woman in the car. Fairly clear that is was justified.
The third was a random pedestrian that cops hit with their car as they were pursuing a suspect. IOW, a random auto accident guaranteed to occur sometimes because cars are dangers and cops drive cars (so "justification" is irrelevant).
