Questions about crime and safety are very common on the board and certainly understandable. Remember though that Realtors are legally prohibited from saying 'that's a bad area' or 'that's a good area.
All we can do is refer you to objective sources where you can sort out the data yourself. I like the crime mapping site mentioned below - www.CrimeMapping.com
I also think there's value in driving through neighborhoods to get a feel for whether YOU feel comfortable. If you see areas with tagging and bars on the homes, then you might question the neighborhood. If the area and sidewalks are clean, and the homes well maintained, you will likely get a good feel.
