One thing I think would be nice to see in-game would be a semi-permanent consequence for raiders and criminals in that you must put in much more effort to punish others for crimes when you yourself commit crimes. Sort of like even if someone can't find them and summon them or stock them, they can bring the evidence to a courthouse of sorts to be recorded into the legal system as a permanent demerit against them until they make reparations to the proper parties for their crimes. It could even act as an invisible Law & Lore delevelling, and make it much more expensive for them to buy their way out of the stocks, put someone in the stocks, and upkeep their claim.
Another thing could be that other characters on the same account as a criminal could "inherit" a certain amount of the guilt, since they are associated in some way with that character. And also, perhaps buying someone else out of the stocks and then having more crimes recorded against them will cause the character who bought them out to fall under suspicion as well?
it could be a way for even those who can't go out and kill the offender to get revenge in some form.
