As with any city, there are websites that you can utilize to gather info. on crimes.
Our out-of-state clients, when researching our areas, have pursued reading the local newspapers online, checked with the local police departments, Megan's law, check the ratings of the local school districts, and most of all an Realtor that a specialist in that particular area.
A Realtor can direct you away from particular areas/properties of concern. Even at that, it is best to educate yourself so you don't have rely on other's instincts of what is a good area or bad.
