Dan Wallach, PhD, Associate Professor of Computer Science at Rice University stated in his Mar. 18, 2004 testimony before the Ohio Joint Committee on Ballot Security:

“Regardless of whether the software in the Diebold or other voting machines is improved to better resist attacks, bugs will always occur and the risk of tampering cannot be overcome. In particular, we believe that while ‘logic-and-accuracy testing’ can sometimes detect flaws, it will never be comprehensive; important flaws will always escape any amount of testing.”
