I’ll give you all a quick tip. If you are thinking of traveling through, staying in or moving to a particular city, just go to the city’s page in Wikipedia and scroll down to the demographics section.
Stay out of Pine Bluff.
City Data is a good site too.
Another way to tell is to visit the local hospital ER after about midnight.
If it’s a steady stream of perps and cops, stay away. Double so if the local PD actually has an office in the ER.
