In "In the Pale Moonlight," when Sisko orders Bashir to prepare biomemetic gel, Bashir responds that he'd like that order in writing, and Sisko complies. Two questions about that: 1. In the real life militaries of today, can a subordinate demand of a superior officer that they put an order in writing if they feel that the order is to do something questionable? 2. What good does it do to have an order "in writing" when "in writing" means "electronically on a PADD"? Is there anything to keep that electronic copy from mysteriously being deleted next time Starfleet starts asking questions?
