right but either way, there is no method a voter could use to verify that their vote has not been changed. the only thing we have is evidence that the machine or the stack of ballots have a trusted chain of custody.

so i am confused about this talk of being vigilant that your vote has not changed, when you are forced to trust the system. if there was evidence someone tampered with the paper stack or machine, there is no way to know YOUR ballot was changed. and most likely your vote will have to be thrown out.
