All good points. I suppose it irritates me because the needs of the disabled are very often an afterthought in the modern world and in this story the same was true again. It also plays into my general frustration that Keenser is a senior officer (and in STiD it looks like he might be the assistant chief) but he is consistently portrayed as a dogsbody. If they just want him to be a light comedy relief then stick to that. If they want him to also be a senior officer, they should also portray him as such instead of just calling him one and portraying him like a junior officer or crewman with cutting one worders and mild comedy antics.
