Well, If it was here, I would call the cops, since it is unlawfull to carry a weapon that is not in a rangebag or thus.
So the thoughts would be that that is a threat, and the police better fix it.
Note: the police dont even carry guns in Norway when on duty, but keeps them in the cars
As an competition shooter, I do transport firearms from my home to the range on a regular basis, and they are always in a sleeve, inside my rangebag, and that is often inside a bigger bag, since I need a lot of extra stuff as well.
This is a setup that makes society feel safe, and it works equally well for hunters and competition shooters that. Basicly the only time I see gun in holsters are at the IPSIC matches, and they are at a approved and secluded area.
I deel that here it works very well, atleast for us Norwegians.
