Yes, that is indeed the purpose of guns.
Ordinary NZ Police personnel are not armed, but arms are available as required, and there are specialist 'Armed Offenders' squads for serious threats.
Yes, New Zealand teenagers are allowed BB guns that are not very high velocity (e.g gas or electric). Most leading brands will have an age limit for their BB guns and that will still be a factor if you are trying to buy one.
Yes if you have a gun permit.
In the US, yes. Other places, maybe.
No. Children, many mentally disabled people, criminals, and other mentally insane people should not be allowed to have guns for fear of them hurting others or fear of having to kill them to prevent harm to others.
In Canada, the kinds of guns that shops are allowed to carry for sale are only hand guns and semi-automatic guns. Fully automatic guns are not allowed to be sold.
Yes, but in time they had to surrender them.
No. They were not allowed to be involved in combat, however they could load guns, be there when people were killed, but not be allowed to kill them. Even though they were allowed to be spies and be tortured, fly aeroplanes to the front lines and build ammunition and guns.
guns?? I don't even think your allowed guns!
The short answer is no, unless you have a firearms collector's licence. A fully automatic weapon is a restricted weapon and unless you have the correct licence you are not allowed to import them or own them. The collector's licence is difficult to get and restrictive.
Yes, you can ship semi automatic bb guns to new zealand but not fully automatic ones
potato guns are not allowed to fire projectiles. that would make them illegal, but you can have one
They are allowed.
