First NEVER EVER FIRE A WARNING SHOT!!! sure way in most states to go to prison! if its serious enough to fire you better be in enough fear to be shooting to kill!
Next, any weapon is an advantage, so is always a good thing. is it absolutely necessary? No. If you carry a weapon, from a walking stick to a .45 1911A1 be able to use the weapon competently and understand that the cops will be asking questions. please consult an attorney in your state or country and find out what the laws are on self defense and what they are about carry and use of any weapon! also check on city and county/provincial laws to! OC spray and tear gas are illegal in some counties and cities and even some country's I understand. but then so is caring even a small pocket knife...UK has some stupidly insane weapons laws for instance.
Well said Australia have extremely strict laws as well. From a logical point of view I can see why they came into force and overall for the vast majority of the population the laws have made no difference. We simply don't live in a culture where having a weapon is necessary or even practical. What this does mean for us is that a lot of weapons - guns in particular - are limited to the criminal fraternities and most people in the day to day lives never come across them. On the other side of the coin, sadly it does mean a lot of us are lacking on the specifics of the weapons or their uses. For instance, if you put a gun in my hand and told me to flip off the safety or release the magazine, I'm more likely to shoot myself in the foot turning the gun over like a rubiks cube than I am to know how to work the damn thing. Cyriacus is based in Australia as well and whilst I don't know if he has any history of living in the US, it does mean our understanding of the specific laws with regards to firearms will be a touch hazy at best.
All that said, as a martial artist, it's a total pain in the butt that I need to go through police checks and file a bajillion bits of paperwork in order to get even metal training weapons!
