Gun laws mostly just keep guns away from law abiding citizens that you needn't worry about in the first place.
Not exactly... when you remove guns from a country completely, and control their sale through detailed verification procedures and requirements, you actually remove the entire problem. You can't go to a gun store here and buy guns... nothing. You can't even just go buy bullets. When those facilities are not available, actually criminals tend not to use them because just being caught with them puts them in jail.
Yes, removing weapons doesn't fix criminal behaviour, but it removes a massive threat from society as a whole, especially when police have them and nobody else does.
To get a pistol here, you have to be a member of a pistol club. You have to apply for the pistol and go through ASIO checks, so the same as your FBI. You are then granted a license to buy that weapon. Most people leave them at the shooting club, because its just not worth having them at home with multiple safes for gun, ammo, parts, etc... then police randomly dropping by your house to check their security at any time they desire.
If you fail to turnup to your shooting club to fire the weapon, the weapon gets removed from your possession, hence you no longer have a reason to have a gun as your not using it for sports shooting at a registered club.
Australia has extremely little gun related violence as a result, thus very little deaths due to such things... and I mean little. It is the equivalent of New York city having 10 gun related deaths a year. That is the difference removing them completely has on a country.
If your a farmer then you can be licensed for a rifle, obviously reasons being on a farm for culling, etc... otherwise there is no chance you will get a rifle or be able to hold a rifle at your home without massive required security to be installed first and again, randomly checked on by police at any time.
America is so used to them, which is why as a country they couldn't imagine being without them, because the logic kicks in that criminals will have them... but that's not logical at all, because when you remove them from a country, it means you remove them all, then control the little that are allowed into the country.
The USA will never change though... because the NRA is to rich, to powerful, to far embedded into the countries political system.
The USA as a majority agree that weapons cause more harm than good, but nothing changes!
Crime still happens, but crime is then reduced to bashing, etc... worse case scenario, stabbed, but even knifes are controlled here... though still a problem with teens that they are quickly fixing. The point is, is that you are more likely to live from being beaten up or stabbed, than from being shot. It takes a lot more effort to beat someone physically or stab, than to stand back at a distance and pull a trigger. Put people in both situations, and the majority will steer clear of options 1 & 2, but 3 with a gun is easy... hence why we don't have them in this country.
