Maven and most of the Black-Briars (Ingun Black-Briar seems like she could care less about their status and seems to be the most stable of them, of course she talks about poisons and about how many thing can kill you but she is an alchemist so of course she would be interested in that crap because what if she opens an alchemy shop one day and her first customer is a guy tasked with clearing out bandit camps? Those facts about poisons would sure come in handy for that.) Maven because she acts like she owns everything in Riften.
The Silver-Blood Family For the same reason as the Black-Briars.

Last but not least . . .
dogs because they like to jump in your way.
Lets not forget guards and every other civilian for running in front of you as you are firing arrows at a dragon and Talos help you if one of the civilians is hit or even dies from an arrow because you will be fined for murder or even assault.
