Well back afew years ago Australia's gun laws were like the US....in other worlds we had Pump Action Shoties and Assult Rifles left right and center..
Then over a period of afew yeatrs we had afew massacars, with up to 10 people killed but nothing "major" enough to change the law.

Then one morning this lovely man named Martin Bryant decided to march into the Tourist town of Port Arthur and let loose, with a rifle...I cant remember the exact number but he managed to kill 30 something people.....and when he was driving away from the attack he saw a mother and her little girl so he stoped the car hoped out and show them both @ point blank.....

We  put him in Australias Highest Security Prison...which has a reputation for the prisons being....err.....a little friendly with each other....forcefully....if you get me Admin.
