Unarmed options in Norway
A buddy has been having lots of interesting interactions with Iranians at church in Norway. He is looking for a source of pepper spray, which is moderately illegal; I don't think he's going to find much.
So, the next best thing would probably be something like an ECQC class. Do we know any competent trainers in Norway or Finland?
Norwegian shooters "aged" out...
The competition shooters I knew of in that part of the world have retired/died. But, he might inquire at gun clubs to openly ask about retired military and/or other martial arts. Since the mass murder incident several years back, I am not sure what or how the laws changed in that part of the world.
I can think of one or two options: fire extinguishers, which could be useful in several scenarios, and for individuals the aforementioned walking stick. There is a certain strength in numbers if the group is committed to one another.
Some places really suck, from my point of view. Defensive actions will be seen as offensive, e.g., the country where Great Britain use to be and France.
