You want to find out everything about someone? (Police arrests, family, history of living locations, sex offenders list, etc.)
Not free, of course.
No stalkers will ever use it, of course.
No serial murderers will be interested, of course. ("Find me the location of all Sarah Connor's in Los Angeles.")
No criminals will use it for identity theft, of course. (Or answering the "what is the name of your cat" question to get into your email.)
Nothing could possibly go wrong!
