What if he has a pair of psycho-killer, robotic androids hiding in plain sight?
He's a normal old shopkeep in a wooden cabin. I don't think he can afford those.
*joins argument*
These are 3 people who don't seem to have anything special, and are wearing the standard sector uniform.
He owns a bunch of weapons and other things that you don't know about. Why would he feel threatened about that?
Because you can point a bow right at him and if he moves an inch, you'll put an arrow in his face?
Unless his mask can deflect arrows, in that case we can put an arrow in his chest.
