No. This is not logically true. The main reason is that the transparency
imperative is multi-layered. We demand a hand-countable paper ballot
because that is what is easily understood.

Also, from a practical standpoint, your theoretically perfect DRE can't
exist -- at least for long. This is because electronic components tend to
remain current only for a short period. This means that review is
constantly needed. A "perfect" system could become un-perfect with a new
release of video sub-system.

Another factor is auditability. The vote count must always be able to stand
up to audit requirements. This is much more difficult to do for a DRE.
There are lots of ways we could devise for auditing DREs, but it is
difficult to do this without running into great expense, and/or compromising
voter privacy.

Again, this "what's to gain" argument is irrelevant. What's to gain by
making legal code easily available to everyone? It doesn't mean the legal
code will be made perfect. Can you imagine what our legal code would look
like if only authorized people and select corporations could see it and
control it? I think there is a better chance that it will be improved, but
that's not the main point. It is, as Lillie pointed out, a requirement of
self governance.

Irrelevant. No one is making the claim that they ensure all the bugs will
be found and fixed.

Irrelevant. Security of the voting system requires a multi-layered
strategy. Open/disclosed source is only one key component of this strategy.

We handle this as we handle the myriad of other specious complaints about
our project -- we've heard all these and more almost daily for some years
now. We walk through the explanations over and over.

About two years ago, I had a very interesting discussion with an executive
of one of the major vendors where this came up. It was almost as if he
wanted to cut a deal. [paraphrasing] "Hey, if we go for open source maybe
we can do away with this stupid paper trail requirement."

Transparency requirements and auditability requirements necessitate a paper
ballot. I don't rule out the possibility that a paperless system could be
sufficiently trustable in the future. Clearly, we don't know how to do this
right now.

The hardware would need to be of a public design before we could even begin
to talk about such a system, imo. I note that in Irwin Mann's 1993 paper on
"Open Voting Systems" he says, "no proprietary parts." But he still
specifies paper ballots.
