From what I can see, the guy dropped his knife and walked out, maybe he got arrested once he got outside. The fact that he's robbing a store while out for a walk with his pet chihuahua suggests mental illness. So actually yeah, no harm was done, no shots were fired, the situation was de-escalated, I call that a success.
It's absurd to me that that the default policing response to someone drawing a knife has become "shoot them until they're dead". De-escalate, FFS. That's what you're supposed to learn in your training.
Reminds me of this clip from a while back:
The British mentality towards policing is very different to the USA. Also, it’s better but it wouldn’t work in the USA. The citizens are more heavily armed in some areas than the police. It’s f***ed up.
