I wonder how courts will ultimately classify AI face recognition when it becomes attached to lethal devices. Tripwires attached to a claymore fall under boobytrapping laws under arguments of reckless endangerment. I've heard it reasoned as there's no mind behind the assault and so it's reckless even if it harms someone breaking and entering. Facial recognition gets closer to an intelligence behind the weapon, but a less than human intelligence (less than canine?). At what point does your "tripwire" have enough intelligence to be legitimate under castle doctrine?
