I'm betting the Commander was not fired due to Weapon Sight Gate. But, it is possible & probable it did draw some attention to him. And, taking a look at his role/duties caused other shoes to drop.
I've been through a handful of career reviews after allegations were made against me. The toughest one for me to deal with was due to an anonymous complaint made against me for inappropriate sexual behavior with staff. I acted like it didn't bother me - though I was very embarrassed by the allegations. And, it hurt that someone would do that to me. Fortunately, an investigation showed I was innocent. And, as if some Karmic Wheel of Justice were involved, my administrators promoted me the day after the investigation report was released.
