The technician who altered the 14 year old tabulating computer in Hocking County Ohio on Dec. 10 has repeated his efforts for witnesses. It's hard to tell exactly what went on due to sloppy, or at least non tech savvy reportage or editing.
It proves nothing. Either he altered the vote or he didn't. If you believe one, he was simply clarifying his actions to put doubts to rest; if you believe the other, he was creating a storyline to cover his deceit.
