See photos below - a couple of 54-year old women from Black Box Voting bought $12 worth of tools and in four minutes penetrated the memory card seals, removed, replaced the memory card, and sealed it all up again without leaving a trace. This experiment shows that the seals do nothing whatever to protect against access by insiders after testing, and the seals also are worthless in jurisdictions like Washington, Florida, California, and many other locations where voting machines are sent home with poll workers for days before the election.
The Busby-Bilbray contest in San Diego now has proof that the optical scan machines sent home with poll workers subjected the tamper-friendly memory cards to an non-recoverable lapse in chain of custody. The recipe for tampering has been on the Internet for over a year: http://www.blackboxvoting.org/bbvreport.pdf
The photos below blow apart claims by elections officials that voting machine "sleepovers" -- sending voting machines home with poll workers for days or weeks prior to elections -- are secure because of seals over the memory card.
But then Black Box Voting purchased an optical scan machine and obtained discarded voting machine seals from King County, Washington. Here's what we found:
See the memory card: It is the item in the slot that says "this side up." Diebold's first line of defense is a metal door that pivots down over the memory card slot.
See how the door works: The hole in the right side of the door is over-large, so you can move the right-side bolt in and out at will. Therefore, they seal the right-side bolt.
See the plastic seal: This plastic seal was used by King County. It had been broken and discarded, so we used the high-tech method of putting an orange rubber band on it to hold it together for this demo. The seal is pointless anyway, as you'll soon see.
