The laws and attitudes to guns changed in Aus when we had dickheads killing as many people as they could to set a record. The breaking point was the guy that went to a tourist spot and shot over 30 people including a mother and baby girl with one shot. When they caught him he asked if he had set the record for the most killed. It shocked our whole nation and now its even against the law to hold a cartridge unless you have a gun licence. My kids know how to shoot and gun safety but if they took one of my empty cartridges to school there would be a big drama.
