That is their prerogative, however I should assume being able to divine the culprit would be far more useful than attempting to piece together what happened after the fact.

As for animating a skeleton, there is no spirit involved with that. It is simply instilling a rudimentary intelligence linked to the caster of the spell in order to accomplish a goal. It is no more binding a soul to something against their will than using the devices we communicate through. The dead are not using their bodies anymore, and they could still serve a common goal.

Banning and regulation are two very different things, however. Should I be elected, I would be more than happy to hear propositions on regulating the practice rather than banning it wholesale.
