I think you may be reading into my position on a separate, but related question: what exactly should be illegal with respect to CSAM possession?
You've pointed out exactly the kind of incoherences in law that I was hoping to bring to mind. Agreed, on the surface there is little difference between possession of snuff vs CSAM. I'm not sure what to do with that observation, though, because I have trouble assessing:
1. Is surface-level analysis is correct? Or is there something bigger at play?
2. What is the appropriate level of punishment vs rehabilitation?
To the first question, there are obvious differences between child abuse and murder, but I can't think of an example in which one of those differences would also lead to a different conclusion about the nature of the recording. Similarly, I don't think the act of recording the crime is significantly changed by any of the differences between child abuse and murder.
With that in mind, what do we do? Do we consider video-taping murder as bad as video-taping child abuse? My own gut-check reveals that I rationally think murder is worse than rape, but then again, rape somehow seems more taboo. If I consider the taboo element, I reach the opposite conclusion: that rape is worse than murder. Adding in the "child" element, I observe a main effect of making everything worse, but the interaction of "rape" getting disproportionately worse than "murder".
Again, this is just me, but I would like to understand where these conflicting feelings come from. My sense is that rape triggers us on a symbolic level... something about Man betraying Woman. I'm old-fashioned enough to think archetypes matter, so I'd like to get a bead on this before formulating any policy opinions.
