As I posted earlier, the only thing these threads bring up is the difference in laws between states and countries. I'm not sure if even our Police Force can carry stldrmgl level of weaponry publicly , never mind privately, definitely not.. Obviously our equivalent to SWAT teams do, but citizens in Australia are not allowed to carry weapons, if you do you are in breach of the law.
As for a man or a woman carrying a concealed handgun then you are in breach of the law, if you use it, even in self defence you will probably have to face a murder charge or at the best manslaughter. The last one in Adelaide that I can recall, there are probably others, was a petrol station attendant who was being robbed by an armed criminal, a customer came in, saw what was going on took out a revolver, confronted the person, shots were fired. And to cut the story short, he went to prison for manslaughter.
Knives are also considered lethal weapons and the same law applies.
