I always send my clients to News 9's Crime Tracker site as well. You can enter an address and pull up what crime activity has occurred within a certain radius and time frame. The link is http://www.news9.com/category/161407/crime-tracker.
Family Watch Dog is the website for tracking violent offenders. You type in the address and can see who lives nearby. You can access this site via my website, http://www.HomesWithLeah.com, under the Resources tab.
Hope this helps! Let me know if you have any other questions.
