The mod tells the gunsmith: "the person you investigated does not have a gun" and at the end of the game tells him: "that did not mean he was not mafia though."
One is the mod intentionally giving incorrect information to the players, the other isn't.
The mod doesn't lie to the cop entirely voluntarily, though, and I think it's this confusion that's led people to believe that cop is bastard. The presence of the godfather (or miller, framer, sanities, and the like) in the setup so that the mod could
potentially
lie to the cop
IS
voluntary by the mod. His hands become tied once the setup is approved, however, and the mod has to give results according to role being investigated and, depending on the setup, the other night actions. You don't tell cops someone is innocent or someone is guilty based on what you feel like at the moment unless you want to be called a bastard mod.
You have the point that a gunsmith knows he can potentially get false positives, though (the false negative you describe, too, but less frequently), and in a normal game the godfather is not immune to the gunsmith.
