Quote...."Ok, nobody had their guns taken, they were just forced to surrender them or go to jail."
Also not true. You could surrender your guns via the "amnesty" that followed the Port Arthur massacre, or if it was legally held with a valid license then you could keep it. Simple plain easy to understand fact.
There are still a few of these no longer legal assault rifles and handguns in the general public, however the number "before" the amnesty was already very low and most, about 80% of those were handed in and bought from the owners at a very fair buyback price, and in a lot of cases they got more for their guns than they paid for them.
It is now illegal to import or buy from any source an assault (semi auto, or fully auto) rifle or handgun, and to further this it is now also illegal to use these at any Gun range. (Forces, Security and Police exempt) So if you own one and are not in the armed forces or police force, you "legally" can't use it at all.
So, still to this day, nobody has had their guns "taken" from them.
PS, not everything in Australia is trying to kill you. (now I am talking animals)
