If you stick around here for a while you’ll find that I am not a “gun them down” person, the police serve one purpose, the courts another.
We don’t really know what the officer saw, it could well be that the kid was super dumb. Thought that he pulled a pistol from the truck and brought it up in front of him before turning to run.
About this stuff happening too often, I spend more of my time worrying about how innocent people are affected by police mistakes rather than if a criminals effective punishment was too sudden and too severe. They are all mistakes and require correction, but it’s hard to get worked up emotionally for a criminal vs the guy that was incorrectly served a no knock warrant and killed in the process. I’d also love to see real statistics on police interactions, I think that the error rate is exceedingly low, but because we are generally more aware of each mistake it seems that the rate is increasing when it is not. This perception bias is easy to document in violent crime, but I haven’t seen statistics that are verified for police encounters.
