Saru: We are officers of Starfleet.
Kal: Prove it.
Saru: You have already identified our ship.
Miner: Anyone could be flying that ship.
Tilly: Starfleet Regulation 256.15 'Officers shall display behavior befitting an officer at all times' which is why we're not freaking out right now by being held at phaser-point by a bunch of strangers. It's actually really scary so could you please lower your weapons or, I don't know, tell us your names so one of those things isn't true?
