>> To me this is the logical outcome of cops hyperventilating that everyone wants to hurt them and everyone is a criminal.
You’re painting with a rather broad brush. I have read about cops who seem to be as you say — but all the ones I know personally are NOT like that.
I take these cops-vs-bystander stories on a case by case basis and examine without prejudice the FACTS that are presented. The cops are not always right, but neither are they always wrong (as you seem to suggest).
In this case IMO the shooting was justified.
I am a harsh critic of police and mostly do not take their side but in this case (and based solely on what is reported here) it looks like a good shoot. If more facts come to light, I may change my mind.
