Very good post, onetrack.
As a gun-owner and active shooter, I must say that we don't need that aspect of 'American Culture' imported here, thank you.
Most of the shooting I do (both pistol and rifle competition) is on a range under controlled conditions.
Occasionally, a farmer or grazier will ask for help dealing with a population explosion or feral animal problem.
The problem is dealt with clinically, methodically and humanely.
Unfortunately, there's a certain ethnic minority here that think 'packing a piece' enhances their masculinity.
We then end up with a tit-for-tat where "I need one to protect myself and my family" is often heard - and so it goes on.
The Police are doing their best but...
I'll say it again, we don't need that crap here.
