What are the Real Numbers?

I swear most people tend to dig statistics out of their asses. Ninety percent of the sex offenders released from prison never offend again. I’m also sure that those who do, didn’t have the family or community support to assure that he/she wouldn’t re offend. I’d like to find some way of explaining the facts to people without them getting angry or argumentative. The media has done a number on this Country's will to be forgiving with a great deal of bogus propaganda. Changing people’s biased opinions will be no easy task. Do you have any suggestions as to how to dispel the myths and lies that have been imposed on the public by political circles and the media?
