According to the presentation, they requested 10 consecutive years of INS records, and that was the only week missing in the batch of records.
Ten years is 520 weeks. One week out of 520 is 0.192307692%.
The obvious questions are, (1) is it true? (2) is there an explanation? (3) who had access?
Of course, even if a video exists of a dude tampering and removing, that still doesn't begin to prove the case. It would just be a tool to convince a judge to dig in further.
We would need the rest of the story ... the actual document(s) on file with the State of Hawaii, etc. E.g., while a forensic examination of the WH BC PDF is pointless, an examination of the original paper record at the HDoH might turn up something interesting.
