I guess the problem is one of legal attribution.

If a human takes responsibility for the AI's actions you can blame the human. If the AI is a legal person you could punish the AI (perhaps by turning it off). That's the mode of restitution we've had for millennia.

If you can't blame anyone or anything, it's a brave new lawless world of "intelligent" things happening at the speed of computers with no consequences (except to the victim) when it goes wrong.
