UESP has this list of illegal actions one can perform:
- Stealing items or horses
- Pickpocketing (although just looking at someone's inventory is not a crime)
- Killing farm animals
- Starting a fight (but not a brawl)
- Killing a non-aggressive character
- Dropping a weapon outdoors in a major city can result in a warning from a guard, refusing to pick it up will result in a bounty
- Transforming into werewolf form in public will give a 1000 gold bounty
- Eating a corpse by using the Ring of Namira
- Shouting in a town may result in a warning from a guard.
However, they don't specify what bounty is associated with every action. Does anyone have this information, or could they build and provide it?
