    It is absolutely the wrong thing to say that shop=firearms means "a shop
    that sells whatever the local law means by firearms". This is a
    general principle in OSM that we define something and then expect
    mappers to use the OSM definition, not local language.

Though if some specific term is primarily legal term and has crazy
definitions varying across world - then using a different term is a better idea,
if such term is available and is less confusing.

I think that's a good approach in this case. Laws and regulations often prefer technical-sounding terms like "weapon" and "firearm" over more colloquial terms like "gun" in order to precisely redefine them within the scope of a particular law. So when data consumers see "weapon" or "firearm", they may be inclined to think we're specifically referring to that law, but we send craft-mappers out into the field, not government inspectors.

The problem with relying on laws to define the plain meaning of a term is that most laws aren't intended to regulate language. A typical law in the U.S. comes with a definition section that _redefines_ common words so that it can reuse them as shorthand later in the text, but this doesn't necessarily bind ordinary people's use of the terminology. If the law intends to promote consistent external usage of the term, then it'll probably call for signage or perhaps a public awareness campaign.

There was a rather spectacular episode last year when a mapper failed to comprehend this nuance and insisted on redefining service=driveway in Asia based on a definition in an obscure California law about where city governments must build curbs and sidewalks. [1]
