SECTUAL

In the UK you can get a shotgun license and literally buy a million shot guns.
But you have to get a permit for every center fire rifle.
In AU NZ its different.
You have to get a pistol license to do target shooting.
But permit to carry a pistol even cops can't carry off duty its left at the police station.
Close personal protection (bodyguard) requires additional things.
But you can take a samurai sword. Or a pairing knife lol
Just depends how you are using it.

well the most favorite weapon of choice for serial killers is the hammer

I am thinking they know best
