My voting system or the systems in the 4 states I've voted in? Which, I'll remind you, one uses paper ballots.
The year 2000 example I gave was literally what happened in Florida. Besides the chad part (which was a _MAJOR_ part of what I was suggesting as unverifiable), I'm also suggesting that given the close call there were many more opportunities for fowl play or accidents.
Really we don't care about verifiability in elections that went as expected. We care when they are close. Where mistakes make a difference. With thousands of ballots everywhere, it isn't hard for a few to get lost. Also, there were plenty of complaints about the ballot layout and how it confused people (Buchanan). You're also not going to be able to keep an eye on the ballots for 36 days (how long it took before the supreme court got involved).
Unless you have a receipt and a database you can easily access you can't really verify that your vote was counted. I'm not aware of any state that has this.
> it's still worse than a properly run paper system.
I also cannot think of a case where this is being done. I'll also note that according to this list[0], I voted with "Paper and DRE without paper trail", but I definitely did not vote on a piece of paper. I was put in front of a machine, so I'm not sure why this is called paper.
