  1. You know I completely understand wanting public information of a registered sex offender because of their crime/offense, however I think it is bulls$&@ that you guys think it’s ok to post there personal home addresses publicly so that let’s people know exactly where they are so they can harm them.

    1. Who are “you guys”? This is an innocuous “Meet the Authors” page on city-data … did you not realize where you were posting?

  2. Hello. I can’t to your site because I’ve noticed an increase in violent crime in my town and I was trying to get the hard numbers. According to your site there haven’t been any murders here in a long time. But, that’s very inaccurate. I know providing this information is a daunting task. I just wanted to let you know. Thank you.

  3. Something smells funny about all these Russians, Poles, S. Africans and such having such interest in the details of “Race and the American Suburbs” and the details of many things that even Americans themselves rarely discuss or analyze. To what end? Who is paying all these people? Why does much of the site look like it has a nationalist and white supremacist bent…again, if the bloggers and owners are either not American or have deep ties to regimes, countries and movements which are anti-American?

  4. Greetings! I hope this comment finds you well, whoever is reading this. I’m Mitchell Gose, a young person creating a petition to develop more accessible infrastructure for pedestrians and cyclists in my city, I was hoping to inquire if I could use your site as a citation for your traffic statistics and maps concerning accidents involving pedestrians. thank you for your time and God bless!
