Dr. Shiva Ayyadurai, M.I.T. Ph.D., the Inventor of Email issued a response to Maricopa County's explanation as to why the "Verified & Approved" envelope stamps appeared to be photoshopped.
Dr. Shiva was contracted by Arizona auditors to analyze mail-in ballot envelope images and his findings were highly suspicious, to say the least.
Here is an example of one envelope image that may be fake.
A poor explanation from the county raised even more questions from Dr. Shiva.
Apparently, the county compressed the images before delivery to the Senate instead of giving the real unaltered envelope images.
Shiva describes the explanation as "somewhat cryptic", then follows up with questions addressing the SOP for envelope image processing.
