Computerized Voting Machines Hacked

Diebold voting systems critically flawed

...critical vulnerability in Diebold Election Systems' touchscreen voting systems that could allow any person with access to a voting terminal the ability to completely change the system code or ballot file on the system.

How hard would it be for these machines to spit out a 'receipt' for the voter, which would then be put in a regular ballot box. This way, after the election, the results could be challenged by a normal, manual count. It's infuriating that these arrogant voting machine makers dismiss such a commonsense option.
