As somoene with no (criminal) legal knowledge at all and going solely by Russ's own citations for what an "eggshell skull plaintiff" is, it's abundantly clear that this concept exists to allow, for example, someone to get the book thrown at them for deliberately setting off fireworks next to a Vietnam vet who they knew or for whatever reason should have reasonably assumed had PTSD. His reading of it, on the other hand, is that it applies to anyone who's feelings get reaaaaaaally hurt by something, ie him.
