Thank you for giving it a read.
I don’t see a way around counting votes physically under the watch of many observers. As Rafa said, it would have been hard for fraudulent votes to have been cast in that election with so many eyes on the Documents 4.
I think the actual voting must be done with paper and pen and people should have to show ID before they fill out a ballot. This isn’t to say that someone couldn’t create a better digital system one day. I just don’t think we’re close to that yet.
