What about... every other situation in space? One country decides its standard to bring guns into the ISS. Conflict starts on earth. Country with guns now holds hostage other astronauts. Would the gun be smart to use inside a space craft? No. Would the gun work as intended inside a space craft? No. Could it possible cause damage that would kill everyone inside? Maybe. Would it work as a tool to control others regardless? Yes. It seems like you're being willfully naive or are just pro guns everywhere. Even space.
