Just imho, Autumn River is in a great location - new shopping centers, close to the mall, minutes to downtown and RTP. Of course, the employees are not allowed to answer questions about crime, just like they're not allowed to answer questions about whether or not it is a good place for "singles" or "families", so if they seemed evasive, it's a legal thing.
You can call the police district for specific stats on that community, though.
