From A Damaging Paper Chase In Voting by Timothy J. Ryan for the Washington Post comes this piece opposing HR811. Among other things it points out that HR811 would conflict with voting systems that cannot provide a paper trail (like Prime III, an Auburn University project that I am not familiar with and hence do not endorse in any way) or cannot preserve all paper records (like punchscan) I would be interested in hearing the reaction of people involved with punchscan to this piece.
