1. Affadavits are great, and all, but if someone else says something different, then additional evidence is required to determine whose statement is accurate. Given the explanation that those who were there opening envelopes were dismissed, it is completely unremarkable that someone would come in, say something like, "ok, if you were opening envelopes, you're free to go," and then people would get up and leave. Once again, you know an announcement was made and some people left. That's it. Why do people keep holding up affidavits as some holy grail of evidence? Has no one ever lied under oath before? Has no one ever thought they heard something but it was actually something else (ahem...PA postal worker)? Has no one ever mis-remembered what they thought happened? And, by the way, eyewitness testimony is notoriously unreliable.
Activities in this unit reveal how eyewitness testimony is subject to unconscious memory distortions and biases even among the most confident of witnesses.

2. What reason do I have NOT to believe it, given the explanation of election officials?
3. The suitcase/not a suitcase part of this was not at all the point. You said it was improper for ballots to be counted without observation. That is not true in GA. It probably should be, but it wasn't at the time.
