That's crazy. I live in Australia and I only know one person who owns a gun, and that's for feral animal management.
The gun violence problem is wayyyy overblown by the media... if you added up every mass shooting that ever happened in our country it'd be roughly 1-2000 people in the past several decades. Whilst at the same time EVERY YEAR 1.3 MILLION people die in car crashes, 450 thousand die from tobacco usage, 300,000 from obesity, and 88,000 alcohol-related deaths. Imagine if the news ran a headline every time an alchoholic bought a bottle or a fat dude went through the drive through, and did a big piece on the "epidemic" of deep frier violence.
Everybody has an agenda and the powers that be want a disarmed population. Anti-gun people are uninformed alarmists who didn't pass statistics in high school, otherwise they might understand that guns violence doesn't even crack the top 10 for causes of death in the US, but seems to make the nightly news whenever the political narrative ties into their pussy view of the world
