> Your first paragraph conflates the system with the tool.
No, it responds to the claim you made. You asserted that systems are also tools and attributed fault on that basis. Perhaps at least reread your own comment before condescending.
> You are also conflating legality and morality.
Also incorrect. I understood you to be claiming tool vendors to bear both legal and moral responsibility; perhaps I misunderstood. Regardless, my position is that tool vendors bear neither of those more or less unconditionally. The only way a tool vendor can become responsible in any sense (IMO) is if they knowingly and intentionally facilitate a particular outcome. The manufacturer of a hammer, gun, or AI facial recognition system is never at fault for what the user does with it unless they actively encouraged that particular use.
