I think some of the criticism towards Captain Freeman regarding her mistakes in this episode is a bit unfair. All previous
Trek captains have been shown to be fallible in their handling of the crew once or twice:
Kirk hesitated to recognize what a danger Gary Mitchell had become in “Where No Man Has Gone Before”, just because they were such good friends. He was too proud to relinquish his command sooner when he became incapacitated due to the aging virus in “The Deadly Years”. He let his “Obsession” get in the way of rational command decisions in the episode of the same name. And he was kinda selfish towards Will Decker, because he wanted to be the captain of the
Enterprise in
The Motion Picture.
Picard is introduced as lacking some people skills right from the get-go with his aversion towards children. He later falls in love with one of his subordinates in “Lessons”, which is kind of inappropriate. And then in
Star Trek: First Contact he places his thirst for vengeance above his duty to save his crew and the timeline.
I bet if I thought about it long enough I could come up with similar examples for Sisko, Janeway and Archer. My point is, they are not supposed to be perfect and from time to time they just screw up and make the wrong decisions regarding their crew. Just like real people do, whether they are lowly ensigns or highly decorated captains.
Have we actually seen a non-medical science person yet (with black boots) on-screen? I've been looking and everyone on that ship with a blue top has white boots, so far as I've seen. Either they have an enormous medical team on board, or someone forgot to actually differentiate such things.
You know, they actually do seem to be kind of rare. Looking over the screencaps over at
cygnus-x1.net I did find one (!) blueshirt with black boots in episode one
