The reason, Mr. Quail, is this. You have to be able to actually know that person and to be able to demonstrate that you know that person in some way. If you live in the poll, there's a reasonable probability that you know that person. If you work in the poll, there's a reasonable probability. If you're someone from across town—with all due respect to Ms. Bradford—I'm actually not sure how you would know the person other than by the fact that they've presented you with a document.
On your statutory declaration, I'm not sure how that actually proves the person is who they say they are, how it proves that they live where they say they live. It's just you saying, or, more correctly, them saying that they went and stood in front of you and said they were who they said they were.
I don't mean to be disrespectful, because I know you're trying to do a good job. I'm just trying to deal with the basic problem here. On the one hand, we want to prevent voter fraud. On the other hand, we want to do what we can to ensure that everybody gets a chance to vote. We don't want to have one goal destroy the other, in either direction.
