In the States, they’d have tasered him first.

You forgot the part where they would have cuffed him, kick him in the ribs and THEN taser.
No, first they’d have to run him over because he was being menacing with a knife. And we know you have to be standing on top of someone to taser them and wouldn’t want to get too close to that knife. Or cane.
And shot his dog. You have to shoot the dog.
