A couple of weeks ago, we had a terror incident in Melbourne, where a man set his car on fire and started trying to stab people (killing one). The police arrived on scene within seconds, and attempted to stop the attacker using non lethal methods, it was only when it was clear that he wasn't going to be stopped that one of the officers drew their firearm and shot the attacker (apparently only once too, unlike in the USA where they empty their magazine). You can view footage of the incident here: https://www.youtube.com/watch?v=cnk4su6HSHk

The officer only used lethal force when it was clear that there was no other option. I don't want to speculate, but I feel like if this was the USA, both officers would've immediately unloaded their magazines into the attacker, possibly hitting bystanders (it's happened plenty of times before).

Compare that to the USA, where an unarmed Australian woman who rang the police to report a possible assault was shot by the police from inside their car: https://en.wikipedia.org/wiki/Shooting_of_Justine_Damond
