I had dealt with some instances of humans killing each other surreptitiously instead of, for example, in front of the entire mess hall during food service, but most had been pre–memory wipe(s) so the details were fuzzy. It was better to prevent them from murdering each other in the first place, by keeping watch for aggressive or destructive behaviors, things like trying to sabotage another human’s life support pack or poison their water supply. Then you put in a notice to MedSystem to call them in for an evaluation, or reported to the supervisor who moved them to a different section so it would be someone else’s problem if MedSystem couldn’t convince them to stop. But whatever, the idea was to keep it from getting that far.
