The Talons' hit list includes a Gotham City Deputy Sheriff, but why would the city jurisdiction have both a police department and a sheriff's department? Shouldn't it be Kane County Deputy Sheriff?
Well, there is a New York City Sheriff's Office, so maybe it's based on that?
Here's the wikipedia link, maybe it helps:
