Barack Obama's forgeries presented in an attempt to claim legitimacy as president, exposed by Arizona Sheriff Joe Arpaio. Probable cause was found as a result of an investigation into these forgeries, that frauds and felonies have been committed. No one has been formally charged in these crimes yet. Ample evidence is found within the digital file claimed by Obama as his "birth certificate" show that it was digitally manufactured, and not made from any authentic microfilm or paper document. In other words, it was clearly "Photoshopped" as a fake. This is a preliminary step in a criminal case as explained here on ABC news broadcast.
