> So if I run in with a thousand ballots and shuffle them in with existing ballots, unless you can prove that I changed the outcome, that's fine?

A crime is a crime regardless of whether it effects the outcome. It is fairly straightforward to prove that you stuffed a thousand ballets if you actually did that, we just have to show evidence of what you did! It is impossible to prove that you or someone else didn't stuff ballots, because it is logically a possible that it occurred. IE proving existence is something that is possible, proving non-existence is something that is impossible.

I'm saying that there is simply no evidence of wrong doing so the courts have nothing to act on. We haven't even made it to the "should the wrong doing invalidate the electoral process" yet.
