Fair-housing laws prevent Realtors from talking about neighborhood demographics such as crime rates, race ratios,etc. We are legally bound to not discriminate and not just in reference to people, that means neighborhoods too.
Any time you are looking for information about local crime (regardless of the city) look up the county sheriffs office and call them directy. Explain you are considering a move to XYZ location and you want to know the local crime trends (what types of crime and in what areas) the sheriff's office is NOT bound by fair-housing laws and can speak freely on the subject. Then, call your local sheriff's office, where you currently live and ask them the same thing. Then you can compare the two. Greenville County --> http://www.gcso.org/
