There is more to what's coming out about Maricopa County than the missing files and refusal to produce images of the routers. There was a lot of so-called old fashioned tampering of the actual ballots. Seals were broken on a lot of the "ballot bags," and the total counts on the bags did not match how many ballots were actually in the bags. The actual ballots were fewer than the slips attached to them in almost all cases, meaning ballots are missing because they were removed and likely destroyed between the first tabulating in November and the Audit underway today.
Also, a number of the boxes where not sealed at all with tamper-proof tape, but ordinary packing tape instead. Ballots that were signature matched exist and can be paired with the envelopes, but were separated to make checking them much more difficult.
This isn't supposition, this is actual evidence coming out.
