In the novel Who Censored Roger Rabbit?, 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]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?
