As an Australian, I certainly wouldn't want to swap for the shitshow that is US gun crime.
The US is obviously worse, but to claim Australia has control of gun violence is kind of silly. It's clearly out of police control.

From your link, 11 gang murders in two years seems pretty good to me.
Personally I'd consider that pretty under control.
I certainly don't live in fear of gun crime here.
