I think it has more to do with a lack of cojones myself.
I'm not normally interested in investigation episodes, it's one of the reasons why I can't be bothered with cop shows, but what I enjoyed about this episode is the fact that it focuses on Shmully and Seven's emotional reaction to a crime which has not been proven. The fact that Kovin turns out to be innocent and ends up dying because everyone was ready to judge him without trial is a dark twist, it is not something I'm used to seeing on Trek.
My biggest problem with the episode is how Seven's infraction from last week is glossed over at the beginning.
I'm ready to give her some latitude. She's been behaving herself lately.
So Seven's rehabilitation into the normal crew has happened off screen between last week's episode and this one? That completely undermines the impact of the previous episode.
