Since people dont seem to think much of it, I'll explain why making an unarmed claim as mafia is asking for death, so long as you cannot consistently deny a gunsmiths existence/ability.
Normally, a player has an about 50% chance of having a weapon. That doesnt mean much. its usually either a powerrole or mafia, with the former being more probable due to mafia making up far less than half the population.
Naturally, the confirmed town result is a bit more favourable, but thats not particularly relevant for the scenario here.
However, once a no-weapon claim has been made, being found with one is an instant bust. A sane villager wouldnt lie about that, so it must be scum.
As such it is always more attractive for a gunsmith to target someone with such a claim, making it even riskier when it's fake.
There is an over 60% chance of a town gunsmith existing (assuming Ginyu set up completely randomly) and mafia doesnt have access to anything fully confirming roles until after the officer died.
The closest things they can have to countermeasures for gunsmith is an agent hiding on the only person to ask for such a check and not seeing them visited by anyone and a security guard consistently targeting the 1 mafia that made the claim (cannot be themselves).
PlayerOa claimed after their security guard had just died and its extremely unlikely the last member is another guard (if its Oa he needs to find the actual gunsmith in order for it to work). He's basically never mafia.
I've taken off my tinfoil hat. We're not targeting any of Sub, ian and Oa until a gunsmith claim tells us to do so. It is good that the most suspicious people among us could clear themselves this way so we can find the actual mafia. Also, slight FoS at everyone keeping the PoE open and not wait for a gunsmith claim or extreme situation where we actually need to be suspicious of the people with such a claim since there is noone suspicious or neutral left. You're just asking for a misslynch.
