Doesn't really matter where you live guns are a part of society here... not as silly as the USA but firearms are still common. Most licensed owners are responsible. I was licensed without ownership... used the clubs firearms... didn't want them on my premises.
Not long ago (about 10-15 yrs ago) there was no real arms control so there are a lot of illegal arms still in the possession of people with no intention of using them but simply haven't declared/surrendered them. These are the ones most likely to eventually end up in the hands of criminals.
All cops and some security guards carry firearms. For me that took some getting used to!
Having said that I've never seen any criminal activity with firearms but I've known two in Aus who have been innocently caught up in armed robberies. Its an unlikely event for most of us.
