Diebold Premier Voting Machines Have Delete Buttons

Report: Diebold Voting System Has 'Delete' Button for Erasing Audit Logs

"But the most startling information in the state's 13-page report (.pdf) is not about why the system lost votes, which Threat Level previously covered in detail but that some versions of Diebold's vote tabulation system, known as the Global Election Management System (GEMS), include a button that allows someone to delete audit logs from the system.
Auditing logs are required under the federal voting system guidelines, which are used to test and qualify voting systems for use in elections. The logs record changes and other events that occur on voting systems to ensure the integrity of elections and help determine what occurred in a system when something goes wrong."
