Q; Why are some weapons locked away in the weapons room, and others are handy behind a wall-panel in Shuttle Bay 2?
A; No reason why they shouldn't be, really. Some might wonder why weapons should be freely available when there are civilians about, which I rebut with the query; what civilians? Not serving Starfleet personnel, surely? Even Mr Mot (as in "That's a nice haircut - Mot!"), one imagines, needs severe vetting before being allowed to wield his scissors. Anyway, anyone so inclined could bonk one of security on the head and grab a standard hand phaser just like the one's in Shuttle Bay 2. It would make practical sense, though, to keep heavy-duty hand weaponry in secure accommodation.
