Just as an FYI, agents refer home buyers to on-line information of subjects related to crime, safety, neighborhood demographics, schools and other "personal" preferences. The Federal Government has a statute that wants to make sure that real estate agents are not influencing your buying decision by providing "non real estate" related information.
With that said, the website Tony provided is excellent. Know that you can Google crime stats for any area or zip code. You may also want to call the local police station in the area to ask any questions.
