Because of this issue, many departments put in much stricter protocols for dealing with this kind of material. Only certain people would be exposed to classify/tag it, and these people would only hold that post of a limited period of time. The burden on those people doesn't change, but it can be diluted to mitigate it somewhat.

Its a real and sad problem, but not one that I think can be fixed with technology. To much is on the line to allow for a false positive from a hallucinating robot to destroy a person(s) life.
