Not humanoid but https://youtu.be/0rliFQ0qyAM
Wow. Reminds me of https://youtu.be/9fa9lVwHHqg
Fluid access to handguns and military style weapons is an intractable problem with nothing more than the example of virtually every industrialized nation on earth besides the US to go on for hints towards improvement.
AI wielding handguns is nothing , wait until they build skynet and invent time travel. Might as well give up now
To paraphrase the joke that's been going around about Children of Men / Britain, perhaps in Terminator it's just California that's chose to be like that because they kept building the stupid robots for the next VC injection.
What's the joke?
That can easily be solved by outlawing them. Just like it has been solved with handguns everywhere except the U.S. which keeps refusing to realize that their 2nd amendmend is just harmful. Luckily it's about guns and not about robots, so at least they will be able to regulate that.
Worse - fragile world here - wait until humanoid robots become as cheap as drones and everyone can buy them. How many irresponsible drone pilots and drivers do you see? Just wait until they can have humanoid bodies walking around at their disposal.
