Why are computer scientists upset by DRE voting systems?
Computer scientists, as well as voters, are upset by paperless DRE voting systems because we know that even a beginning programmer can write code that displays votes one way on a screen, records them another way, and tallies them yet another way. This can happen for a variety of reasons, including software and hardware errors, or “hacks” installed into the voting machines. These problems can occur even when voting machines have been thoroughly inspected and tested. DRE systems experienced a number of problems already in the 2002 elections, and we see this only as the tip of the iceberg.
