I glanced through and i agree with fox here that, it should be removed. However an alternate option it could be overhauled maybe as a science upgrade? allowing you to target a player and if they try to draw a gun or shoot you shoot pretty much wild west duel.
The other is removing it and possibly designing a better auto-targeting system either as a upgrade again or hos captain gun only etc that when its turned on it will do what the turrets do check ids look for weapons etc and evaluates on that.
So for example you got a civilian beating a doctor with a toolbox it will see that someone is hitting another with a none contraband item and tasers them. My second example is the opposite almost a traitor is running at you with a energy sword the gun goes lethal and fires.
hell you could even implement this that the guns themselves can't shoot unarmed people if there deemed not a threat.
Side-note: the not firing on none threats made me think of you could scan your id into a taser laser gun etc making it imprinted to you so no one can just pick it up and fire it. of course a higher rank can remove that id so it can be used by another or unlock it and emag can unlock it as well. would make for some interesting rounds.
