Given "mind/body dualism is a bust", several legal systems has already decided this to the effect of: all conscious entities running on the same hardware shall be punished for the crimes of any one entity, but the punishment generally cannot be the termination of all entities.
Decisions touched on collective punishment, vs how do you distinguish between similar-but-different instances forked at different times, etc.
Now DID/MPD/whatever-it's-called-in-your-jurisdiction, does not have the same characteristics as brain uploading, but it does have overlap in terms of forking (and the forks may be very similar or extremely different), pausing of instances, time dilation from running slower and some perceptual but not legal aspects of moving between hardware (20 year old body vs 50 year old body has different capabilities and possibly even gender) with no perceived interval.
Given uploaded consciousness and punishing the hardware - can you avoid punishment purely by moving your instance to another location, and will upload hosting services have and/or need extradition treaties that could force you back to the hardware that did the crime (and does that even hold any meaning in this context if you could send a fork back and both be punished and not-punished at the same time).
]]>Shadowrun would have a Call of Cthulhu crossover book.
We don't need CNG for that one, there's probably others but Dark Conspiracy was the one I had fun playing - depending on the GM/players the tech isn't as widespread as Shadowrun, and the unspeakable horrors may be humans, aliens or incomprehensible multi-dimensional beings who want to eat Seattle for unknowable reasons.
The setting is closer to north american laundryverse than NM though, so doesn't meet OGH's original question.
