I think it would be inappropriate for me try to educate anyone on the use or misuse of DNA data. The following link is to a site that provides a look at several aspects of DNA use. Both positive and negative aspects are discussed. The information appears to be designed for a "lay person" audience, so most people should be able to understand the concepts discussed. Anyone could "begin" their education here. http://www.geneart.org/genome-toc.htm Thank you for your time.
