I read the news. The investigation cleared the officer, said the shooting was justified. I agree.
I took a citizens training course taught by the police. One of the evenings was spent with the firearms trainers. We did a simulation of laser pointer handguns playing cops. The computer or the instructor ran random variations on similar starting circumstances for us so we didn’t know whether to fire or not. We had to watch the suspect and guess his intent by subtle actions. Tough being a cop.
We learned that it was impossible to stop a knife attacker in less than 21 feet. You may hit but he/she can still kill the innocent officer. It was interesting.
When a man refuses to throw down the knife in four seconds and appears wobbly, it may mean he has a little hearing problem (maybe he did but he is not blind!) and it may mean he is drunk (he was, and that means danger to cops from guys with knives.)
I am sure the cops in Seattle know this too. Don’t expect any lawsuits form this.
