In the novel [Who Censored Roger Rabbit?](https://en.wikipedia.org/wiki/Who_Censored_Roger_Rabbit%3F), rather than the 'toons being indestructible as in the movie, they can produce doppelgängers that are a mere shell of the being, which fade out after a few hours. One character commits a murder and uses a special high-quality doppelgänger to establish an alibi. Now this begs the question of why not *have the dop commit the crime* and then run off to expire, so it can't be tied back to him at all? In David Brin's magnificent [Kiln People](https://en.wikipedia.org/wiki/Kiln_People), people make golums of various fidelity to do chores or even work; some have factory workers generated daily to expire rather than re-merge at the end of the day. In a Larry Niven story, the character had his memory restored to an earlier backup so he was unaware of his escapades. In *many* stories, we have robots, usually programmed with safety features so you can't just order one to rob a bank or kill someone. If people *could* create disposable copies, or order about robots complicated enough to pull off a bank robbery, it would have the general property of allowing people to get away with things. How could society prevent this misuse, or cope with such reality?
