PREYING ON THE VOTERS: FLAW FOUND IN TOUCH-SCREEN MACHINES.
The most severe security flaw ever found in a voting system has
been discovered by a Finnish expert working for a non-profit
group. A professor of computer science at Johns Hopkins told the
NY Times that he, "almost had a heart attack," when he learned of
the problem. This was not some innocent design error that wasn't
caught. Diebold, the company that makes the machines, built in a
secret "back door" to "update the software." It could be opened
in minutes if someone knows the code. Don't worry, the code is a
proprietary secret of Diebold. Of course, there was that 2003
fund-raising letter to Ohio Republicans from the Diebold CEO that
said, "I am committed to helping Ohio deliver its votes to the
President" http://bobpark.physics.umd.edu/WN03/wn121203.html .
