This report by Black Box Voting is pretty devastating.
Due to contractual non-performance and security design issues, Leon County (Florida) supervisor of elections Ion Sancho has announced that he will never again use Diebold in an election. He has requested funds to replace the Diebold system from the county...
A test election was run in Leon County on Tuesday with a total of eight ballots. Six ballots voted "no" on a ballot question as to whether Diebold voting machines can be hacked or not. Two ballots, cast by Dr. Herbert Thompson and by Harri Hursti voted "yes" indicating a belief that the Diebold machines could be hacked.
At the beginning of the test election the memory card programmed by Harri Hursti was inserted into an Optical Scan Diebold voting machine. A "zero report" was run indicating zero votes on the memory card. In fact, however, Hursti had pre-loaded the memory card with plus and minus votes.
The eight ballots were run through the optical scan machine. The standard Diebold-supplied "ender card" was run through as is normal procedure ending the election. A results tape was run from the voting machine.
Correct results should have been: Yes:2 ; No:6
However, just as Hursti had planned, the results tape read: Yes:7 ; No:1
The results were then uploaded from the optical scan voting machine into the GEMS central tabulator, a step cited by Diebold as a protection against memory card hacking. The central tabulator is the "mother ship" that pulls in all votes from voting machines. However, the GEMS central tabulator failed to notice that the voting machines had been hacked.
The results in the central tabulator read: Yes:7 ; No:1
This videotaped testing session was witnessed by Black Box Voting investigators Bev Harris and Kathleen Wynne, Florida Fair Elections Coalition Director Susan Pynchon, security expert Dr. Herbert Thompson, and Susan Bernecker, a former candidate for New Orleans city council who videotaped Sequoia-brand touch-screen voting machines in her district recording vote after vote for the wrong candidate...
One thousand two hundred locations in the U.S. and Canada use Diebold voting machines.
