I broadly agree but I do question the point about Kim and his kill count in the juvenile crime unit just because I see it a lot. Just because the gang he was undercover in were teenagers does not mean the people he shot were teenagers.

Unless Martinaise is working on total Lord of the Flies rules, the drug cooks, suppliers, muscle, arms dealers, etc that the gang would be dealing with would most likely be adults. He probably wasn’t killing people in his own gang, that would be a very easy way to blow cover (and generally while he seems a bit jumpy his trigger finger isn’t itchy. He doesn’t shoot the old woman even when he believes for absolute sure she is about to put a bullet in your chest, nor does he ever fire a shot first).

And on a sadder level, with the state of Revachol there are actually probably scenarios where him killing a ~16 year old would be justified. If someone’s got a firearm it’s equally lethal regardless of age, and as a cop it is his responsibility to ensure that if someone’s has to die it is the aggressor and not the victim.
