beSpacific links to a Diebold voting machine security report.  The post links to an interesting California Voter Foundation press release as well — California first in nation to implement electronic voting reform (May 4, 2006):

"All 58 California counties are on track to deploy new or upgraded voting equipment that guarantees every ballot cast will be backed up on paper that voters can verify before leaving the polls. Fourteen counties acquired over 40,000 electronic voting machines in recent years, all of which are being replaced or retrofitted with printers in time for the June election, making California the first state in the nation to reform its electronic voting systems after widespread deployment of paperless e-voting machines."

So much for the paperless society.
