Did you know that the National Center for Missing and Exploited Children (NCMEC) says their are about 750,000 sex offenders across the country, which they did phone surveys for the numbers, but they don't tell you how many are duplicates due to aliases, misspellings and human error, how many are deceased but not removed from the registry, or those who have moved from one state to another but have not been removed from the state they no longer live in!
